An eyepiece for deep sky objects helps you see faint objects in the night sky. It magnifies the image of the object, making it appear brighter and easier to see. Many deep sky objects, such as galaxies and nebulae, are too faint to be seen with the naked eye.
An eyepiece helps you see these faint objects by magnifying them.
Celestron Omni series eyepieces offer a 50 degree apparent field of view, perfect for the Moon, planets, and a plethora of deep sky objects. The premium four element optical set is finished with multiple layers of high transmission coatings for clear, sharp images.
The edges of the optics are blackened for increased contrast. The Omni eyepiece body is made of aluminum. A two step anodizing process results in a beautiful matte finish that resists reflections and glare.
Each eyepiece in the Omni Series includes a black rubber eyecup. It can be left up or folded down for better observations while wearing eyeglasses. Models with a longer barrel (15 mm, 32 mm, 40 mm) include a rubberized grip for non slip handling during observing sessions.
The insert barrel is threaded to accept 1. 25 inch filters. The eye relief for this 6mm model is 5mm.
I bought this Omni Plossl to use with a f 14 90mm Mak-Cass telescope and a 76mm f 9. 2 reflector. Views are crisp and sharp. I get a 2. 4 degree field @ 22 power in the reflector and 1. 3 degrees @ 39 power in the Mak-Cass.
This eyepiece is great for maximizing your field of view, both with long focal lengths and short. The eye relief is long but easy to hold. I would recommend this eyepiece to anyone with a 1. 25 focuser scope for a low power, wide field eyepiece.
I purchased two of these 32mm Omni Plossl eyepieces for use in my Televue Binoviewer. I have a much older third 32mm Celestron Plossl purchased a decade ago. The new 32mm omnis are attractive and the optical quality matches the older one I have.
The image is crisp and clear across the field and both eyepieces match very well in the binoviewer. However, one of the two had a very poor blackening job on the inside of the 1. 25 barrel with shiny metal showing through on several areas.
Approximately 50% of the surface had a poor coating. One was perfect, the other was not. Since the optics were fine, I unscrewed the barrel and re-blackened the inside surface with three very light coats of ultra-flat black spray.
This indicates that inspection and quality control needs to be improved. This is an obvious imperfection and easy to correct. I have many Celestron eyepieces and this is the first one with a such a glaring flaw.
Nice, stiff and heavy construction but optics rather medium quality. Relatve to price (~33$) I would say good enough. As an affordable choice is good but if you want top quality with a serious telescope go for something better.
Actually the problem is located in the center of the glass (slightly distorted imege) while the surround field of view is relative good.

25 in – 8-24mm is a super-premium fully multi-coated zoom eyepiece which allows for expanded magnification options. This eyepiece is compatible with any telescope that accepts a 1. 25-inch eyepiece. Pick the best magnification for your object and enhance your view! The fully multicoated optics provides sharp, bright and detailed observations so the user can thoroughly enjoy the viewing experience.
Instead of giving it to Goodwill, I upgraded an old Tasco refractor to 1. 25 hardware and bought this as a first eyepiece. It replaced the weakest part of the system and I ended up with a reasonably good, usable instrument.
Comes with a large rubber eyecup which makes viewing really easy, especially for the grandkids who could never quite master the original, tiny eyepieces. It’s the only eyepiece I need for my purposes.
Worked so well, I ordered a second one and converted an old Sears model. Now the kids don’t have to fight over a spot in the viewing line.
Used the eyepiece with my Meade 125 mm ETX. Meade. Excellent optics and the zoom eyepice worked perfectly with the telescope. Used it at 24 mm, and 8 mm and DID NOT HAVE TO REFOCUS. Star images were pinpoint! The eyepice is solidly made, and the adjustment from 24 to 8 and back is smooth with the right amount of friction.
Looking forward to using it on Jupiter. Saturn, Uranus, then Mars. Moon was sharp at 24 and 8! Love it at low piwer, to find the object, DO NOT HAVE TO CHANGE EYEPIECES, to use high power. Love it. Great price!.
I purchased my first one several years ago for use in my observatory and my review is below. Recently I have purchased two more, one for my ‘outside’ telescope and the other for my daughter who I gave a 90mm alt/az refr.
In both cases it generally avoids fiddling with having to change eyepieces outside in the dark. It is true that some light is lost in the extra lenses involved in a zoom, and for critical work, if straining for that extra tenth of a magnitude you are better off with a good quality eyepiece of set focal length.
(I use an 25mm X-Cel on the C14 for my lunar occultation observations. ) Having said that though, there is nothing like simply turning the barrel to zoom in on whatever you are observing, and very quickly adjusting in or out to achieve the best framing, or the highest magnification the atmospheric ‘seeing’ will permit.
The low power field at 24mm is a little narrow (40 degrees) compared with the standard 50 degrees of Plossls or the 60 degrees X-Cels etc. but much wider than the 30 degrees of one competitor. (If you want to crib an extra few degrees in field width, you can always go to the upmarket model – It depends upon how much you are prepared to spend.
) Once you start ‘zooming’ the field progressively increases to 60 degree width at 8mm. The zoom effect is truly mind-blowing as my daughter attested. With slight adjustments of focus as you are zooming the images remain clear and sharp from edge to edge.
NEGATIVES: 1. On my new unit, the rubber eye cap partially pulled off twice when removing the dust cap. Some rubber glue applied with a toothpick ensures it stays in place. (My daughters, and my original one is okay.
) 2. Half way through the zoom a tiny oblong spot becomes visible as the focus passes through a glass surface within the eyepiece. (Tested on a blank white background. ) My old unit is okay. 3. The operation of the zoom function is stiffer but acceptable.
(It will probably free up with use. ) 4. Focus needs adjusting during zoom.
Celestron X-Cel LX series eyepieces offer a 60o apparent field of view, perfect for the Moon, the planets, and a plethora of deep-sky objects. The premium six-element optical set is finished with multiple layers of high- transmission coatings for clear, sharp images.
The edges of the optics are blackened for increased contrast. All seven X-Cel LX eyepieces sport 16 mm of comfortable eye relief, and are parfocal, which means you can switch out eyepieces within the series during observing sessions and little or no additional focusing will be required.
The X-Cel LX eyepiece body is made of black-anodized aluminum. The pop-up eyecups make it easy to adjust the height for different users. Turn them in one direction to extend the length, and the other direction to provide a flat surface, preferable to most eyeglass wearers.
A treaded rubber grip around the center of the eyepiece barrel offers secure handling, even in moist conditions or with heavy gloves on. The 1. 25” insert barrel is threaded to accept filters.
I have tried several Barlow lenses on my telescope, all under 25 and all with limitations – particularly chromatic aberration which limits the ability to focus down to the best resolution. I splashed out on this more expensive 3x Barlow lens following ‘best buy’ advice on line.
It is certainly noticably better. The image is almost as large as my x5 Barlow but there is almost no chromatic aberration and the detail is clearer. The result is a brighter sharper Mars, and because of the magnification, a less pixelated one.
It seems paying a little more is worthwhile in the world of lenses. My only caveat is that the image quality is now limited not by the eyepiece but by the rest oif the telescope. (I still cannot resolve surface detail on Mars, with my 6″ reflector.
) Any further improvement will require a lot more money! If you can afford it, I recommend this lens which looks and feels like a quality product and does the business.
Nice construction. Feels sturdy and good quality. I have used this a couple of times on my Celestron 127SLT and with an eyepiece attached this was great to view Mars. While still somewhat a dot in the sky, it was a bit larger dot that just with the eyepiece.
My main reason for purchasing was to use in with my DSLR for planetary imaging. However, I have not been able to get a good viewing like this but I don’t believe it’s the fault of the Barlow lens and rather user error.
Still a great piece to have in my telescope tool box.
This 18mm eyepiece is my second LX eyepiece. I also have the 12mm LX eyepiece. These eyepieces for telescopes and Celestron ED spotting scopes give a wide and bright image. The screw up eyecup adds to the convenience of these highly recommended eyepieces.
The 1. 25″ diameter barrel 82° Series 8. 8mm Eyepiece from Explore Scientific is engineered to deliver a wide field of view with a long eye relief, making it ideal for planetary and deep-space observations.
Its long eye relief makes it extremely comfortable during long observation sessions while offering you the ability to utilize the averted vision techniques that allow you to see faint details of elusive objects like wispy nebulae and galaxies.
Viewing comfort is also optimized for eyeglass wearers. Proprietary EMD anti-reflective multi-coatings ensure bright, high-contrast images with true color transmission across the entire wide field of view.
To keep internal reflections to a minimum and improve contrast, the inside of the barrel is blackened, as are the edges of the lenses, to minimize the scattering of light within the lenses themselves.
A fold-down rubber eyecup prevents stray light from leaking into the eye, further boosting contrast. All eyepieces in the 82° Series are parfocal, so there will be little to no need to refocus when moving from one focal length to the next.
This eyepiece features a textured surface for a sure grip when changing it out, and it is argon filled for water and fogproof performance when used in extreme temperatures and climates.
Now that I’ve got this Eqmod thing working properly, I think this is the only way to go, as opposed to using the hand control which I was originally doing or connecting through the hand control with printer cable which I also tried.
It took me a while to configure everything and was only able to do so with the help of Dave at High Point and help from Pegasus Astro. I’m not that computer literate so I didn’t know I needed a driver.
And this lack of knowledge was reinforced by Windows 10 saying on the one hand that no driver was installed for this device and on the other hand that no driver was needed for the device. Probably everyone else in the world would know that a driver is needed.
I didn’t. But now with this EQMOD USB Stick connected, working with my HEQ5 and Stellarium is amazing. I can’t even imagine going back to the hand control.
Just bought the 100 degree Explore Scientific kit with 5. 5, 9 and 14mm focal lengths as well as the ES 30mm 82 degree eyepiece. All performed excellently on my first dark sky outing with my 16” dob.
When combined with the ES coma corrector, the wide field views were flat and pin-point perfect from one edge of the field to the other in all the eyepieces. Seeing Stephens Quintet in the same field with NGC 7331 using the 30mm 82 degree was pretty cool.
The ES 30mm 82deg is a bit lighter than the ES 25mm 100deg, so is easier on your telescope mount, without compromising too much on true field of view. All of these eyepieces are nearly perfectly parfocal, which simplifies observing enormously.
I was pleasantly surprised that ES was able to maintain this across there 82 degree and 100 degree eyepiece line. I also bought the ES 2x 2” focal extender, and similarly had excellent results observing small planetaries and the Andromeda galaxy globular cluster G1 at 654x using the 2x focal extender with the ES 5.
5mm100. One note: my low profile focuser couldn’t travel far enough out to bring any of the eyepieces to focus. Once I inserted the ES coma corrector this problem went away. I had the same problem when combining the 2x focal extender with these eyepieces without the coma correct.
To remedy, I simply had to fix the eyepieces in place slipped 1/4” out from sitting flush against the focuser tube. If you have a low profile focuser that does not have enough outward travel and don’t have the ES coma corrector, you may need to add a 2” parfocal ring to some or all of these eyepieces to allow them to sit slid out a fraction of an inch in your focuser tube.
A minor issue – more of a problem with the focuser than with the eyepieces.
See the whole picture with Ultima Edge. These flat-field eyepieces were designed to provide an ultra-sharp, ultra-clear, crisp image from the center all the way to the edge of the field of view. The 30mm Ultima Edge eyepiece features fully multi-coated optics and a 9-element, element lens design, maximizing light transmission.
The Ultima Edge 30mm has a generous 70° field of view perfect for viewing planets, stars and the Moon’s surface. This eyepiece provides low power magnification, perfect for deep sky objects and a bright detailed view of the moon’s surface.
The 30mm Ultima Edge eyepiece’s main housing is machined from high grade aluminum with a black anodized outer surface. Its 2″ mounting barrel is internally threaded to accept standard 2″ filters and adapters.
It is compatible with 2″ star diagonals and focusers. On the exterior of the eyepiece, you will find a uniquely designed, molded rubber grip ring for non-slip handling during observing sessions. Viewing through the 30mm Ultima Edge eyepiece is comfortable for both eyeglass wearers and non-eyeglass wearers alike, thanks to the rubber eyecups and long eye relief of 22mm.
I upgraded from the cheap stock eye pieces that my scope came with and this 15mm is my new go to ep. I also got the 10mm and the same applies: The fov is perfect, the eye relief is very comfortable (I don’t wear glasses), and image quality is leaps and bounds better.
The “flat field” feature is also pretty cool, a crisp image from edge to edge. I’ve never experienced a multi-hundred dollar top of the line eye piece, but I can’t imagine how much better it can get than this.
For around the $100 price range this is a phenomenal eye piece you’ll be happy to have.
The Celestron version of the UFF works well in my refractors and SCT. I like that it’s light and that the field is nice and flat. My only disappointment is that there is more distortion moving toward the edge of field than there is in the same design 24mm eyepiece.
The moon is not round when moving away from the center of field. The moon stays round off center in the 24mm. I’m still happy with the purchase.
With two motorized observatories I’ve owned for nearly 40 years, a roll off built in 1982, and a dome just completed in 2016, and probably 34 eyepieces mostly Naglers, differences are obvious. To me, the two matching 15mm Celestron Edge at around $150 each in my Televue Binoviewer did no harm nor displayed any chroma, and at my age the thrill is gone of spending $450 each on an eyepiece.
With their 66-deg apparent field of view, our Expanse wide-field eyepieces will definitely turn up the Wow! factor in your deep-sky observing experiences! Imagine taking in objects like the Andromeda Galaxy, the Double Cluster, or the star clouds in Sagittarius in one sweep! With an Expanse in your focuser, you can! Expanse oculars have big eye lenses and great eye relief.
Eyeglass wearers can view the entire field without removing their glasses. All eyepiece elements are fully coated, with the outer lens multi-coated for additional light transmission. Each 1. 25″ aluminum barrel is threaded for filters and internally blackened to eliminate internal scattering.
And their fold-down rubber eyeguards enhance contrast by blocking stray light. With our Expanse eyepieces you get a super wide field of view and superior optical performance. You also get a bargain!.
It was time to upgrade my eyepiece inventory. I had the old Plossl eyepieces with 52 degree AFOV and little eye relief for higher magnification. These have 66 degree AFOV and a much more comfortable 13mm-18mm eye relief.
I was looking for a great eyepiece upgrade without breaking the bank, and these eyepieces were perfect! I was able to see the Sirius Pup for the first time with these eyepieces, after trying for a few years.
Got the entire Expanse EP set (6mm, 9mm, 15mm, 20mm) as part of the Deep Sky Explorer’s Kit. This is my favorite of the those 4, at least right now. I have used it in both my old XT8 classic Dob, and my new XT10i IntelliScope Dob.
Both have a 1200mm focal length, so this EP gives 60x mag in both scopes. In both scopes, this gives a 66 degree AFOV. In the XT10i, it gives a TFOV of 1. 1 degrees. The Sirius Plossl 25mm EP gives a 52 degree AFOV and a 1.
08 degree TFOV in the XT10i. Despite the small difference in TFOV, the difference in AFOV is amazing. The 20mm Expanse is just better to look through than the 25mm Plossl. The feeling is much more immersive, and the wider field of view makes finding faint fuzzies a little easier.
Also, one can view the entire full moon in this EP, more comfortably than the Plossl, as this EP’s higher mag makes the image less overpoweringly bright. A recent session at the local park using mostly the 20mm Expanse allowed me to find around a dozen or so DSOs that I had never seen before, such as NGC 7009 [Saturn Planetary Neb.
], NGC 253 [Sculptor Galaxy], NGC 6543 [“Cat’s Eye” Neb. ], and M36, M37, and M38 [open clusters in Auriga]. A definite improvement over the 25mm Sirius Plossl if you an afford it – and hopefully you can, as it is reasonably priced, especially if you buy the whole set of 4 Expanse EPs.
Moreover, eye relief on this and the other Expanse EPs is noticeably more comfortable than with the SIrius Plossls [not that those are bad]. Good job, Orion! Looking forward to more nights using this and the other Expanse EPs.
I have owned very expensive eyepieces, those that sell for $100 – $500. Some of those had a slightly wider apparent field of view (AFV) but yielded the same image resolution as the Expanse series. These eyepieces are truly a bargain as well as of very high quality design and workmanship.
The 66 degree AFV is significant and at the same time large eye lenses on all the eyepieces as well as creativity in the 6mm and 9mm optical configurations allow very generous eye relief on all of the Expanse series.
Lenses are multi-coated, give a tack sharp edge at the field of view and light throughput is outstanding. Rubber eye-cups can be folded down for eye glass wearers and these are threaded to take 1 1/4″ filters.
They are relatively light in weight so there are no re-balancing issues with their use. These are the primary eyepieces that I use in 1 1/4″ format and as I said, I have used some of the ‘high end’ eyepieces that don’t make a marked improvement compared to their high prices and added weight.
I would rate these fine eyepieces a solid 10 based on precision optics and views along with value!.
The 1. 25″ diameter barrel 68° Series 20mm Eyepiece from Explore Scientific is a wide-field telescope eyepiece designed for detailed close and deep-space observation. It uses low-dispersion, high refractive index glass with anti-reflective fully multi-coated optical surfaces to ensure bright, high-contrast images with true color transmission across the entire wide field of view.
Its wide AFoV and long eye relief makes this eyepiece ideal for comfortable viewing for extended periods with or without eye glasses. The contrast is enhanced by a fold-down rubber eyecup that prevents stray light from leaking into your eye.
The eyepiece features a textured surface for a sure-grip when changing it out, and it is argon-filled for water and fog-proof performance when used in extreme temperatures and climates.
I had be looking into upgrading my eyepieces and had researched several options. Everything I read about the DeLites indicated that they were what I was looking for. The DeLite really is a delight to use.
Crisp, clear views with pin point sharpness across the entire field of view and excellent contrast. I really liked the adjustable locking eyeguard. Most other brands use a simple foldable rubber eye cup and nothing else but I wanted something that would help limit stray light.
Played around with it till I found a position I liked then locked it in there. This eyepiece was an introduction to me to the DeLite line and I’m planning on getting several others.
I use this eyepiece with my Celestron 8SE for viewing solar system and deep space objects. I am extremely happy with the optical quality. The focus is sharp edge to edge. The build quality is excellent.
I envision the eyepiece lasting many years. A nice bonus is that, with registration, the product carries a lifetime, fully transferrable warranty. I plan to buy more Explore Scientific eyepieces.
I know I did a review yesterday, but everytime I compare the E. S. 16 to another lens, it is clearly superior. Tonight was the 18 & 13. 8 meades SWA’s from yesteryear. Lenses I thought were pretty good 60 degrees from the early 1990’s.
The E. S. has the sharpest star images that only elongate a little at the very edge. Really overall better than the Meades, or the TV Panoptic 15mm. This is the best at any price.
Providing performance at a reasonable price for most beginners, the Explore Scientific 52° Series 30mm Eyepiece produces a very low power in most telescopes, and is a perfect addition to your observation arsenal.
Outfitted with a generous 52° apparent field of view, it employs a flat-field lens system that is treated with their proprietary Enhanced Multi-Layer Deposition (EMD) coatings to produce bright and clear views that are flat edge-to-edge.
This lens design makes this eyepiece ideal for averted viewing techniques in which you view dim deep sky objects, such as wispy nebulae, indirectly using the portion of the eye that is most sensitive to light.
This model of the 52° series is offered here with a standard 1. 25″ barrel to make it compatible with the most popular size drawtubes and accessories. The eyepiece is argon-filled and O-ring sealed to be waterproof against condensation and dew and resistant to fogging.
A textured collar provides a slip-resistant grip, especially in cold weather or while wearing gloves. A fold down rubber eyecup makes it comfortable and easy to view through, with or without eyewear.
I had to buy a new usb cable for my ZWO that I tripped over in the night and broke. They weren’t in stock so had to wait a bit for it to arrive. In the meantime I found some on line for half the price but they weren’t OEM.
So I grabbed them up. My cable from HPS came today and it is much better than the others I bought. It’s a flat cable which makes it more flexible than the braided ones I bought. I had plenty of time to cancel my HPS order but they have never let me down and I’d rather spend my them.
Besides my clumsy feet might strike again at any moment. Thanks to HPS !.

I can not attest to the quality of manufacturing and material. But I will say it feels nicely heavy and well built. I read a posting earlier, saying it was just as good as higher priced eyepieces. With some doubt I compared it with a Tele Vue of same magnification.
I recently purchased the Celestron 32 mm Eyepiece for my older Bausch and Lomb telescope. This company provided the 1. 25 option which was the only company that did. It is a perfect fit and the bonus was the outstanding quality of the eyepiece.
The view is crisp, wider and better than the original. I am very pleased to have a functioning telescope again with great viewing potential. I love it!.
The Luminos series eyepieces offer a wide 82 field of view in both high power and low power models, allowing you to make the most of your telescope, whether you own a short, fast refractor or a Celestron EdgeHD telescope.
The optical set consists of six or seven elements (depending on the model) and is fully multi-coated for crisp, sharp views. All six Luminos eyepieces are parfocal, which means you can switch out eyepieces during observing sessions with little or no additional focusing required.
The Luminos eyepiece body is made of polished and anodized aluminum. A rubber grip runs around the equator of the eyepiece, giving you a secure grip and an easy method for raising and lowering the retractable eyecup.
Simply twist the rubber grip to adjust the height of the eyecup. The insert barrel is threaded to accept filters.
Like a few other reviewers I’ve seen, I received this 23mm Luminos as part of a pkg with the 9. 25 Edge telescope. I didn’t have really high hopes for it since it was packaged with a scope, not usually the best source for eyepieces.
But I was pleasantly surprised, now I consider it a great eyepiece. The 82 AFOV is quite impressive and plenty wide enough for me. And the stars, planets, and the moon are razor sharp on nights with good seeing.
To be honest, I’ve not really checked to see if the stars at the very edges are as sharp compared to the ones in the center. If I’m going to be looking at stars that far away from the center I’ll move the scope over to them.
I’m sure if the stars at the edges weren’t sharp, I would have noticed THAT by now. I only have a small collection of eyepieces so far, including ones by Stellarvue (8mm, 82) and Pentax (12mm, 60). I plan to add the 15mm Luminos, 10mm Luminos and the 31mm Luminos to this collections soon.
They aren’t cheap, but they’re not that expensive either compared to some really premium range eyepieces.
Solid eyepiece as in good views. Solid eyepiece as in heavy weight. The 82 degree view is very nice. Feels like looking out of a picture window. Used with an OG C8 and an f6. 6 refractor that are both fairly forgiving so I can’t comment on any abberations that might come with faster scopes, but I didn’t notice any in moon or star views.
No easy planets to check out for me at this time. Very sharp image until extreme edges. Weighs a good bit so it did make my refractor focus lock do work.
I am very impressed with the performance of the Luminos 31mm on my Lasered 8” Celestron SCT mounted on a GEM. The Edge to edge views of the Moon are simply breathtaking. I am anxious to see what it can do on diffuse nebulae and galaxies.
The laser puts objects in the view of my 24mm eyepiece about 60 percent of the time, but the Luminos 31’s huge 82degree FOV brings it in 100% of the time. However, as my wife says “It’s a biiiig one!”, I have to rebalance the scope to use it.
I have also ordered the Luminos 10mm. I am very pleased with my purchase and am looking forward to using them both in the very near future.
The Explore Scientific 100 SeriesTM eyepieces are hyper-wide class oculars that can transform your visual astronomy experience. You may be startled at the amazingly wide expanse of inky black sky you behold the first time you bring your eye to a 100 Series eyepiece, and after awhile, you may even forget that you have an eyepiece between you and the universe! With an apparent field of view that is close to the maximum for hyper-wide eyepiece design, objects are not only easier to locate, but for non-driven telescopes the object will stay in the field of view for a very long time before any adjustments need to be made.
Another great benefit of hyper-wide eyepieces is the ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.
This eyepiece is not for the faint of heart. It weights 2. 6 pounds (41. 5oz), So, do I recommend it, yes, with some notes. First, the optical system should be working at least at f10 if you want a relatively pleasing view.
In my 11″ f10 edge, the field of view was sharp out to about 85-90 percent. The view was still pleasing, but not like the view in a 21mm Ethos by Televue, which is sharp pretty much to the edge. Second, with the weight of this eyepiece, you may need to offset by using counter weights, depending on your set up.
For my 11″ a counter weight helps. Third, the cost is really getting up there after the latest price increase. I have been intrigued by this eyepiece for the last couple of years, so I finally bought one (discounted here on ebay).
It does everything I need it to do. Provides me with a wide field of view, almost the maximum my scope will show. the view is very sharp (minus the last 15%. I have no regrets as it fits right in with my shorter focal length Ethos.
I purchased the 12. 5mm model for planetary viewing in my C14 (f/11) and for hunting faint galaxies in my 12. 5″ f/5 Portaball. The physical design and presentation of the eyepiece is very good. The box is sturdy and well thought out.
The new “safety kerfs” are a welcome replacement for the traditional undercuts on modern eyepieces. The rubber grips make holding the eyepiece easy and it doesn’t want to slip out of your hand. On the downside, the luminescent paint doesn’t glow at all unless the eyepiece has been in the sun for a bit, and even then does not last very long.
The biggest problem on the physical design is the eyecups. The rubber eyecups don’t fit well (too loose) and are far too short to be effective. The eyepiece has 20mm eye relief, and the tallest eyecup sits just a few mm above the eye lens.
There’s nothing to rest your head against, making it very difficult to stay centered over the exit pupil. Also, the gap between your eye and the eye cup lets in stray light, which reflects distractingly off of the enormous eye lens.
Optically, the 12. 5mm Morpheus is quite good. It has fantastic control of ghosting and glare, and a nice flat field. The Phantom coatings work wonderfully and yield a nice neutral color tone. At f/11, stars are tack-sharp across the field.
The view is a bit softer at f/5, but that’s to be expected. That said, it’s not as well corrected as, say, my Explore Scientific 82 degree 18mm. Ultimately, I had to send this eyepiece back. Not because I was disappointed with it optically, but because it was just too uncomfortable to use.
The long eye relief is nice, but without any physical reference (an adjustable eye cup) to rest the eye against, the image dances all over the retina, and it’s impossible to avoid blackouts. Moving close enough to the eye lens to use the tallest eye cup as a tactile reference means it’s not possible to see the whole 76 degree field.
The result is an extremely frustrating experience, as it’s impossible to get comfortably centered over the exit pupil and have it sit still. Even when sitting, I was unable to prevent constant blackouts.
I decided to give the Morpheus three stars, because honestly the optics are great, and I really did enjoy the views through it. But for me, the constant blackouts and difficulty in obtaining perfect eye position, were a deal-breaker.
Honestly I bought this EP on a whim. I really wasn’t sure what to expect; I’d bought a Hyperion a while back it was just OK for me and quickly sold it on the used market. Well, the Morpheus is in a completely different class! For its size its suprisingly light in weight yet still very well built.
The overall design is made for incredibly clear and wide views. I have another high end EP in a similar range with an 82 degree FOV and despite the Morpheus having a sllghtly narrower field of view, it beats that one for FOV and clarity in my eyes.
I’m sold on this line and the only thing I regret in buying it is that I passed over them for too long. My goal is to eventually own the entire line.
Concept: It was natural to take lessons learned from the tremendously successful Ethos project and apply it going forward. In the fall of 2008, Paul Dellechiaie was tasked to investigate a long eye-relief eyepiece design in the 70° AFOV range, retaining the key performance goals met with Ethos.
My father named Paul’s design, “Delos. ” Delos is a beautiful Greek island which happens to be the mythical birthplace of Apollo, god of light. More importantly the name was chosen to give recognition to Paul, principal designer of both Delos and Ethos.
I use this in my Orion XT10 dob. At 120X, it’s a great complement to my 17mm Ethos which yields 70X. I’m absolutely in love with the wide FOV and the pinpoint sharpness these EP’s offer. 120X in my scope is great for detailed, higher power views of spring galaxies and summer DSO’s, while still providing great framing.
I was fortunate enough to get very good seeing near Goldendale, WA last Sept. and with a Barlow, got amazing views of Jupiter and Saturn at 240X with this EP. I could make out 7 bands in Jupiter, plus the GRS and a lunar transit.
I could even make out 3 bands in Saturn. I’m completely hooked on this line of EP’s as the spacewalk views they provide is unparalleled. I’m now spoiled by these and have a hard time looking at objects through lesser EP’s.
I’ve had this eyepiece for a couple of weeks so here’s my experience with it: I’m using this 6mm Ethos in an Orion XT10 plus. To reach focus I either use the 2 tube extension that came with the scope or I stick it in the 1.
25 adapter. The adapter that came with the xt10 puts little thumb-screw marks in the side of the eyepiece when you tighten it so I bought the Tele-vue 2-1. 25 flat top adapter which has a brass ring inside it.
That reaches focus just fine as well. I live near downtown San Diego (lots of light pollution) but this eyepiece STILL can resolve tons of stars in the M13 (Hercules) cluster. Empty areas of space look very nice and dark and it pulls more faint stars into view.
Even better then my Baader Hyperion Zoom. The detail that I can now see on the moon when I use this in combination with a baader. 6 ND filter stacked with the Baader Moon and Skyglow filter is absolutely stunning.
I’m very happy with this eyepiece. The Stardust lens case/tube in size D fits it nicely and keeps it safe. Can’t wait to take the scope up to Mount Laguna which is my local Dark Site. Buy one. If you have a dob like mine then it will be near the furthest limit of your focuser but it will reach focus with either the 2 extension or the 1.
So if course it’s great! Just had first light with it, loved how it did on some simple well known visual sights- clusters, doubles, galaxies. Haven’t tried planets or the moon yet, but I’m sure it will be fantastic! This will certainly get used and has a secure place with the other Ethos pieces in my stable.
Some people say the extra weight and $$$ isn’t worth it for the extra wide views, but if you love them like I do, there’s no going back!.
Assuming that you don’t subscribe to the misconception that strong magnification gives better views of deep-sky objects, then our Orion DeepView 28mm 2-inch Eyepiece should excite you. Why. Because the brightest and sharpest images of deep-space objects are obtained with low power and a wide field of view.
And the 28mm DeepView 2-inch eyepiece delivers just that. This 2-inch telescope eyepiece features anodized aluminium housings and a 3-element lens design with multi-coatings for efficient light transmission.
Eye relief is 20mm – a welcome spec for eyeglass wearers – and the rubber eyeguards fold down out of the way if desired. Apparent fields of view is a generous 56-degrees. Delightfully free of pincushion distortion and chromatic aberration, this 28mm telescope eyepiece will impress even the seasoned deep-sky observer.
The barrels are threaded to accept 2-inch filters.
So my eyepiece arrived yesterday and last night had a nice clear sky to test things out. For a $90 dollar eyepiece I was not expecting the high quality views that I this eyepiece provided. The views where crisp and in my light polluted area that says allot.
For my 8″ scope this eyepiece is really outside the limits 41mm max parameters. I am sure at some point I will fork out the $530 for the TeleVue Panoptic 41mm down the road. Till then, I will enjoy this eyepiece.
I should note, be sure the scope is Collimated or this eye piece at this limit for this type of scope may not be crisp.
First & foremost, my review only applies to my experience with using this eyepiece with a 12″ F/5 Newtonian Reflector. I would expect this eyepiece to perform poorly with other F/5 and shorter mirrors too.
I would expect it to perform better with longer F ratio objective lenses or mirrors. It might perform better with smaller diameter mirrors too even if they are F/5. The deal breaker for this eyepiece is that it produces intolerable curvature of field with an F/5 mirror.
“Curvature of field” is when you cannot achieve a sharp focus across the entire field of the eyepiece simultaneously. With this eyepiece – mirror combination if you focus stars near the center of field to pinpoint sharpness, stars halfway from center to edge of field will appear blurry.
If you focus stars near the edge of field to pinpoint sharpness, then stars towards the center of field will be blurry. This effect renders this eyepiece totally useless in my opinion, except for doing the initial alignment of a GOTO telescope in which you don’t care if the alignment stars are out of focus.
Note that “curvature of field” is not the same thing as “coma”, coma is distortion near the edge of field. I was able to achieve sharp focus across the entire field of view with my 12″ F/5 Newtonian by buying a more expensive 2″ multi-element eyepiece.
Living in Wisconsin this year has been a waiting game for trying out new eyepieces: the 2013-2014 winter has yielded very little gazing. However, when the skies finally cleared I tried my Christmas gift Deep View eyepieces and immediately discovered a whole new telescope experience.
With my XT8, I was awarded crisp and expansive views of the Pleiades and the clusters within both Auriga and Perseus! The ONLY problem was that the -5 degree temp stiffened up the eye cups such that they had to “thaw” in order to roll back down for capping.
I am so looking forward to seeing what they offer come spring!.
Ethos eyepieces are currently on long back order Tele Vue is known for its in-house eyepiece and telescope designs by Al Nagler; the development of the Ethos series brings new meaning to the term “in-house.
” The concept for this eyepiece series was proposed by Tele Vue President David Nagler, with performance parameters giving it the fundamental characteristics (the ethos) of a Tele Vue eyepiece: high contrast, comfortable eye relief and full field sharpness.
Control of astigmatism, field curvature, lateral colour, angular magnification distortion correction, and low pupil sensitivity for daytime use were specified criteria. Following Tele Vue’s philosophy of pushing the state of the art, long-time Tele Vue employee and optical design protégé Paul Dellechiaie took up the challenge and designed the basic eyepiece form.
Under Al’s guidance, Paul tweaked his design to fulfill the original goals. While sharpness is inherent to the optical design, contrast is maximized through the intelligent use of flat finished baffles and ultra low reflectance, high efficiency coatings tuned to the composition of each element.
This is an amazing eyepiece. I use it with a 12 dobsonian and the views are absolutely beautiful. Big FOV with sharp stars from edge to edge. Its like looking through the window of a space craft. I have a 9X Explorer scientific 100 degrees eye piece and I love that one too.
The 17x works better for me then the 14x or 20x ES eyepieces. Only drawback, it is big and heavy!.
With a 68 degree field of view, coatings that rival eyepieces costing hundreds of dollars more, and great eye relief, the Baader Hyperion’s are the perfect visual eyepiece, however, their innovative auto-locking 2-inch sleeve supports heavy cameras for a focal projection photography with the appropriate Hyperion T-ring.
Overall I am impressed with the Hyperion series. Mainly due to the modular nature. I like the idea of adding tuning rings and threading on camera adapters. Very sturdy in that respect. In terms of optical performance, I am not so impressed unfortunately.
With the 17mm, I am getting a serious amount of distortion in the outer 30% of the FOV with my f/5 scope. Knowing this is the case with most eps, I was still dissapointed as I had heard it performed better with fast scopes.
So, for me, if the object isn’t right in the middle, it’s not looking good. The other big problem with this ep is the sensitive eyeplacement. Both with my PST and with my Denkmeier bino setup (the sole way I observe everything), you cannot be even a 1mm off-center.
You will get total blackout. It’s easier with binos since you adjust your eye spacing and the two eyes keep things centered. But, if you move your eyeballs to look toward the edge of the FOV, you get blackout.
For me, this is a deal breaker. Also, when you unscrew the lower element to thread on a turning ring, dust and lint can easily make their way into the optical surfaces there. Unfortunately, that is precisely where the focal plane resides.
So, it must be very clean otherwise on bright objects you’ll see ever little speck of dust. This is especially true with the PST and the Sun. Finally, with Jupiter I am getting serious ghosting and reflections.
Optically, when on-axis all images are very sharp and show a lot of detail. I was espeically impressed with the Sun through my PST/Denk combo. But, considering these other problems, I am not going to keep this eyepiece much longer.
This high quality 8-24mm zoom eyepiece from Celestron is an amazingly versatile eyepiece that allows you to choose from a variety of magnifications in a flash. Simply grip the rubberised barrel and turn it slowly while looking through the eyepiece, and then pick the best power for the object you are observing.
Alternatively, you can use the lowest magnification (24mm) to find an object and centre it in your field of view, and then increase the power until the desired view is achieved. It is fast and easy, and lets you examine any object at various magnifications without requiring you to physically change eyepieces.
The Celestron 8-24 mm zoom eyepiece uses premium optics that are fully multi-coated for crisp, clear images. The folding eyecup lets you view with or without glasses, and the field of view (40-60 degrees) works well for terrestrial observations as well as for views of the Moon, planets, and deep sky objects.
After reading a number of reviews where people used this zoom in their Coronado PST and raved about it, I decided to give it a try. I’m not a big user of zoom eyepieces, but they were right – it worked great! Details were about as sharp as with my fixed focal length eyepieces, and the versatility and simplicity of a zoom is a real treat.
I don’t plan to use this eyepiece other than in the PST, so cannot comment on its performance in other telescopes.
I find it to be a great lens. But I’m new to all this does have blurring around the edges. I’m using it 8-in dobsonian and I live in Southwest Florida. So I don’t know if it’s the atmosphere it’s causing it.
But it’s a very smooth transition between 8 to 24. The weight of it helps balance the telescope. Overall I’d rate it a four. An opt has been great.
The Baader Planetarium 17 mm Hyperion 68-degree Eyepiece offers world-class performance and unique photo-visual features. No longer do amateurs need to spend more on their eyepieces than their primary instrument in order to get true high-end performance in a wide-field eyepiece.
Not just a different branded version of their highly regarded cousins, the Hyperion have been totally redesigned to deliver better transmission, contrast and useful new features. Baader Planetarium has worked hard to give the Hyperion the world’s finest optical coatings, superb mechanics and their unique multifunctional design.
As a visual eyepiece, the Hyperion delivers superb sharpness and color fidelity across their 68-degree wide, flat-field even in fast telescopes. In comparison to the Pentax XL eyepieces, the Hyperion matched the Pentax in every regard.
From their superb on-axis and off-axis sharpness to their pitch-black high contrast field, the Hyperion really works. Viewing through a Hyperion is notably comfortable and relaxing due to their forgiving eye-position, 20 mm of eye-relief, extra-large eye lens and an optical design that is free of annoying ‘kidney-beaning’ and blackouts.
This eyepiece is absolutely perfect. It has plenty of eye relief, and a good field of view. Optically your view is real clear and crisp. I was so impressed by the performance of this eyepiece that I bought more of them in different magnifications so I could cover all aspects of enjoying the night sky.
A great price range for this level of performance. In short, these are a must have!.
Lens clarity was less than expected for price. Wide field of view was as described. It’s a rather heavy lens. I did not need a counter balance, but just a word of caution. Using with a 700mm/60mm telescope.
Can see Jupiter and moons but not level of detail I’d like. I haven’t used it to see the moon yet. New moon or overcast.
You’d find 50mm objectives would not allow engouh light gathering at that great magnification. Big dim images are less rewarding than smaller, wider field, brighter ones. With binos, a wider less magnified image allows you to locate deep sky objects as they relate to their neighbours; i.
e. whole constellations make sense, but isolated stars streaking by don’t. Finally, if that 50 50 objective to magnification relationship were useful, pros would use and advocate them. They don’t.
Features include blackened lens edges to minimise internal reflection and maximise contrast, multi-layer coating group on each lens surface to maximise light transmission and contrast, and each Omni goes through a two-step anodising process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces.
Threaded barrels accept 1-1/4″ Celestron thread in filters. Celestron Omni eyepieces are also available in the following focal lengths in a 1. 25” format: 6 mm, 9 mm, 12 mm, 15 mm, 20 mm, 25 mm, 40 mm.
High quality 32mm super-wide angle 2″ telescope eyepiece at an unbeatable price Super-wide 70° apparent field of view gives you that unforgettable lost in space feeling Five multi-coated lens elements made of high index glass deliver sharp, high contrast vistas Luxurious eye relief and parfocal design provide comfort and convenience Beautifully made with machined housings, fold-down rubber eyeguards, and barrels threaded for use with 2″ Orion eyepiece filters Peering into space with a Q70 2″ telescope eyepiece puts your favorite nebulas and galaxies in a wonderful new perspective.
Gas clouds glow and stellar clusters glitter amid a seemingly endless ocean of black space, thanks to the Q70s’ super-wide 70-deg apparent field of view. Each Q70 has five lens, multi-coated, high-index glass elements for sharp, high-contrast images with excellent color correction.
Eye relief is a luxurious 24mm. All eyepieces in the Q70 series are parfocal, so you can change eyepieces without refocusing. Machined housings have fold-down rubber eyeguards and a rubber grip band.
Threaded eyepiece barrels accept 2″ filters. Two end caps are included.
I have all three of the Q70s and have been using them now for about a year in my 10 inch Skyline. The are a good solid eyepiece at a good price and I have no issues recommending buying them. The one thing to bear in mind.
The image on axis is very good, but once you go off axis the stars start to look like sea galls. This happens with all three of the Q70s. If you only look on axis its not an issue, but if you look at the whole image it might bother you.
That is why I would like to add the recommendation that when you buy these, you also buy the coma corrector that Orion offers. When used together the stars off axis are perfect and then the hundred dollar eyepiece competes well with eyepieces at twice the price.
As I said I would recommend these eyepieces as long as you buy the coma corrector as well.
I have the XT8 telescope and this was the first big upgrade I made for viewing! This 38mm monster from Orion is great for deep-sky viewing. This eyepiece gave me the Bode galaxy/cigar in one nice clean view.
Obviously, I only got grey colors from those distant objects so you need filters to get better coloring on those kinds of images but you can easily tell what’s in plain sight. I also look forward to getting a view of the Orion nebula soon.
If you are up in the air about purchasing anything from Orion, don’t hesitate. I have emailed them with loads of questions and they genuinely care more about your viewing than about making a dime. They have a customer for life right here!.
I’ve used this abot a dozen times with three different telescopes. The views were sharp and bright in all telescopes from a sct to a newt and a refractor all different focal lengths. In fact it performed so well I purchased the 2″ Ultra block filter to use with it and that also works great with it.
I plan on getting another Q70 soon as it’s in stock. I your looking for a 2″ widefield eyepiece that doesn’t break the bank this is a great choice. I’ve owned other 2″ eyepieces and this is a better product by far.
Since Tele Vue introduced their Plössls in 1980, they have won praise and patents, including a patent in Japan. Tele Vue Plössls, designed by Al Nagler, have been a recognized benchmark of performance and value in the class of 50° apparent field of view eyepieces.
While the Plössls may be their least expensive eyepiece line, they still enjoy the same care and attention to detail as their most expensive.
I’m using this eyepiece to replace the standard Meade eyepieces that came with my telescope. The clarity is a major improvement as is the contrast. Jupiter, it’s moons, and saturn had a lot more clarity with the Tele Vue Plossl eyepiece.
I purchased this particular eyepiece based on a review I read and my subsequent research. Before this eyepiece I was using a Celestron 20mm EP that came with my telescope. Naturally the stock EP is not of high quality, but it does allow for a remarkable comparison! With the Tele Vue, there is no distortion or blurriness at the edges and no light streaking or fuzziness.
As it was recommended in the review I read, it is best to have one or two low magnification but high quality eyepieces than a bunch of low-to-mid eyepieces because it means you’ll actually use them! I will always go with Tele Vue after experiencing first-hand what high definition looks like through a telescope.
I purchased this to complement my other eyepieces for my Orion 130ST reflector. I already have good quality low power and high power eyepieces so this fills the void for mid power viewing. Starting with first impressions, the packaging and weight of this eyepiece immediately made me realize why Tele Vue has the reputation that it does.
While using the eyepiece, it’s everything that I hoped for. It has noticeably more contrast and clarity than my other eyepieces, including two from the Stratus series. The only drawback at all is that after using larger FOV eyepieces, the 50 degree AFOV seems restrictive.
However, that’s what a Plossl gives you, and keeping that in mind, the clarity is well worth the price of the Tele Vue Plossls. A Panoptic might be next for me.
There are a few things to consider when selecting an eyepiece for deep sky viewing. The most important factor is the eyepiece’s focal length, which determines the magnification and therefore the level of detail that can be seen.
A longer focal length will provide more magnification and therefore more detail, but it will also have a narrower field of view. This is important to consider when choosing an eyepiece, as a too-narrow field of view can make it difficult to find and track deep sky objects.
Another important factor to consider is the eyepiece’s eye relief, which is the distance from the eyepiece lens to the eye. A longer eye relief is important for deep sky viewing, as it allows the eye to be positioned further away from the eyepiece, reducing eyestrain and making it easier to take in the entire field of view.
Finally, the eyepiece’s coatings and optical quality are also important factors to consider. Good quality optics and coatings will help to reduce glare and improve contrast, making it easier to see faint details in deep sky objects.
