Most suffer from variable plossl, svbony, SVBONY Zoom Eyepiece, Zoom eyepiece. You sometimes feel more like you are actually there, in the view. As for "triple testing" eyepieces, that I seriously doubt happens. Waiting Period: We are in continuous production and operate one year in advance. Cons: Slightly soft off-axis performance. But the price is the highest. Bottom Line: A superb eyepiece for 2-inch focusers. Anyway, my main concern was trying to get most or all of the Pleiades in my view. I have the Stellarvue 15mm UWA and it needs some focal length to clean up the field as curvature starts getting beyond tolerable for my eye around the 65-70% mark in an f/7 600mm refractor. Cool, thanks for the info! Call us at: 530 823 7796 Open Mon-Fri 9-5 Pacific Time, 4.0 mm 1.25" Ultrawide angle eyepiece with 82 degree apparent field of view(, 1.25" Ultrawide angle eyepiece with 82 degree, Our EUW eyepieces are now loaded into AstronomyTools database and application. Below shows the 100 degree Ethos alongside the 82 degree Nagler. The eyepiece is turned my 115 into a whole new scope for visual observing. Build quality 2nd to none.., relatively light for it's size.., but most of all the view is spectacular, all the way out to that wide 100 degree FOV. Stars are Nagler-class sharp to the edge even on the Newtonians. and even less can be tolerated in condition of tacking mount. Have fun experimenting! Because they're Stellarvue! Then MyGermanUniversity is the right place for you. Though advertised as 82, Celestrons 15mm Luminos had an apparent field between that of the 76 Morpheus and the other 82 models. This my first refractor, my first telescope with quality optics, my first telescope with a wide field of view, and my first telescope with a decent focuser (among other firsts) so I am very excited and anxious to get my hands on it. Holding your eye in the proper position is way easier. Having tried 52, 60, 70, 76 and 82, I'll stick between 70 and 82.

For planets 30-40 deg. New from SV? The focal length choices seems a bit odd to me: 28mm, 16mm, 7mm and 4mm, but perhaps more focal lengths will fill in the gaps later. Will 1.25 inch eyepieces fit ES coma corrector? I haven't used it in the field and it's pretty heavy but it's my best shot and easy access. The eye relief is comfortable but a bit tight at around 12mm. Accessories, Astrophotography gear, Reviews. It is likely KUO like the WP Meade UWA, who also make the UWAN/PWA. I've had both and they are excellent (and same price)! I've pretty much settled on 68-72 degree eyepieces. Old thread, but thought I would ask here first just in case instead of starting something new Stellarvue is running a sale on a 3 piece set of their 82 degree eyepieces for $292 while ES 82's are on sale for $99 each. Top-ranked German Universities in Munich. Bottom Line: Near-Ethos image quality for less money. It's nominally 1mm more of eye relief, but it seems like more because the edges of the field are just that bit more accessible. The eyepieces rival Televue but they were sold to fund an Ethos. This is why some wide field EP's cost more, some, a lot more. Pros: Good off-axis sharpness and eye relief, but .

At 564 grams even with its 2-inch adapter tube, Stellarvues Optimus is the lightest of the 100 set, a consideration for balancing smaller telescopes. Pros: Very good optics and waterproof construction. The A-T 28UWA/StellarVue 82 and APM 30UFF has already been mentioned in this thread. Introducing the new Stellarvue Ultra Wide Angle eyepiece series.This ultra wide field eyepiece has almost 3 times the area of a 50 degree eyepiece. I recently purchased the 9 mm Optimus eyepiece after my excellent experience with the 20 mm Optimus. Unfortunately EP focal lengths are rarely exactly accurate and in the case of the axioms they were obviously paying homage to the original 23mm axiom and 24mm was close enough to call a 23. For 1.25" 82 eyepieces, I have a mixed set of Televue, ES, and UWA. With a 10 inch Newtonian at an f5 focal ratio, the 50mm eyepiece you are considering will produce a 10mm exit pupil.

The A-T 28UWA/StellarVue 82 and APM 30UFF has already been mentioned in this thread. All rights reserved. They are probably another variation of the UWANs, thought the specified focal lengths have been changed from 7mm to 8mm and from 16mm to 15mm. While the rubber eyecup can fold down, it is stiff enough that it is best left up. Ive never been a fan of zoom eyepieces. This affect is more pronounced in lower magnification, wide-field EP's. Of the lower-cost 82 models, this was a good choice overall for both optics and mechanics. I do most of my observing with 82 degree eyepieces. Field Stop: 13.6 mm Number of Lens Elements & Groups: 7 elements Special Features: Tapered insert tube Comes with Dust Caps? I find that I can use nearly the entire field of an 82 eyepiece for observing an object but the wider field of a 100 or 110 eyepiece does not add much to the field useful for observing the planets and double stars. This counterweight system is used to quickly adjust balance on smaller telescopes when eyepieces of different weights used. But its the design and optical ease of a design that makes an eyepiece good for me. You may see the shadow of the secondary mirror with this eyepiece and exit pupil. You would recognize the names of the OEMs if I told you. You currently have javascript disabled. They are still the best but are expensive. If you're not sensitive to curvature perhaps give it a go but honestly if you have on hand a 2x and a 3x barlow just get the 15mm because then you'll have all three. But I'm thinking a pair of the 16's might make a nice selection for binoviewers. The 28mm has a 2" barrel, the rest are 1.25". 100 degree eyepieces are quite amazing but they are also very large and can be quite heavy. Click here to simulate the field of viewhttps://astronomy.tools/. But I'm interested in the 16mm as I don't have a UWA in that focal length (I used to have the old 5000 series Meade 18mm UWA but sold it). Bottom Line: A well-made eyepiece but costly for the performance. With the 20 mm I will then have 32, 20, 16 and 10 mm equivalents. This is a great moderate power wide field eyepiece for viewing all kinds of deep sky objects, the moon and planets. The 4.5mm Morpheus is sharper than the Ethos SX, by a hair. Drop it in a barlow or a slow Mak and it's tolerable. this IS the best value in an ocular that I have found.., I'm super pleased with the product. What I dislike is decreasing the AFoV when increasing the magnification, the true field takes a double hit. All of my scopes are on manual mounts, so I agree, the larger the AFOV the better. The ES is solidly made and comfortable to use despite its short 11mm eye relief (measured from the top of the eyecup), due to the recessed eye lens (the specs state 15.6mm). I strongly recommend both the 20 mm and 9 mm Optimus. I still focused on the field stop and never got the spacewalk views others enjoy. Thanks! I really like the 82 FoV in my scope, great image, easy to manage and store. I tested nine brands of 82 eyepieces, all in the 13 mm to 16 mm range, a focal length that provides moderate power on most telescopes and so is suitable for all types of viewing. I've had a few of their scopes that are well made, and well corrected, but labeled as someone elses. Don't dismiss buying a used EP out of the Classifieds section - I found two of mine there.

Don't know if this means that that the actual focal lengths are different? But it is an excellent and attractive, though large, eyepiece at a slightly lower price than a Nagler with much better eye relief. Munich, by far the largest city in southern Germany, lies about 30 miles (50 km) north of the edge of the Alps and along the Isar River, which flows through the middle of the city. Yes, for standard 1.25" and 2" eyepiece filters. The 16 and 7mm looked diffierent than these didn't they? The A-T is darn close, but does give more magnification and FOV. Theres a new alternative for the Celestron NexStar SE and NexStar Evolution series tripod a short, foldable tabletop tripod. Very comfortable, bright and sharp. Either model represents an excellent value in a mega-wide eyepiece. There are many really good ones available in this category, all across the price spectrum. That's easier with the smaller size of the 82 Naglers when compared to the 100 eyepieces, however I'm working on that. No question they set the standard. National Ranking. However, on a Schmidt-Cassegrain, with its more forgiving f/10 focal ratio, off-axis sharpness was much better. Heres a low-cost zoom eyepiece that actually works well. I present them in order of increasing price. And the color-coded cosmetics of the SSW series are attractive, though somewhat moot in the dark under red light. Toss-up, both a bargain @ $200. Despite its size and dual barrel, its mass is only 586 grams, less than some of the competitors. Stellarvue 4 mm Ultra Wide Angle 1.25" Eyepiece - EUW-04.. Has similar build quality to TeleVue and has a better feel than its APM counterpart. I have the WO versions of these and find them very good, indeed! FWIW I looked at the Pleiades yesterday with a 32mm Plossl, a 24mm UFF (~65 AFOV) with my XT10 which has the same focal length as your telescope. It just felt like a 68-degree field that was pushed slightly further out. I have a tendency to increase the apparent field as the magnification goes up so I don't have to push the dob quite as much. This eyepiece is ideal for higher power work on planets and double stars since it is very sharp, contrasty and has a generous 82 degree field of view. I'm hoping they will be sharp to the edge at f/7. Both have the same true FOV and cover the cluster nicely. Edited by jrbarnett, 08 October 2014 - 02:40 PM. Cons: Field less than others; eyecup height not easily adjustable. It looks very similar to the Stellarvue 82. I need at least 22mm of effective eye relief. Please note: Internationally, grading systems used at institutions of higher educations may differ substantially. Our EOP eyepieces are now loaded into AstronomyTools database and application. Stellarvue 8mm UWA 82 degree eyepice that has never been used. $65 a piece is very cheapfor these eyepieces, so you did a very good deal there. Very fast shipping and packaging. So from a practical point of view, I find there's little difference in drift time. The Stellarvue 82 is well made, with a compact, solid construction, good 14mm of eye relief (better than the stated 12mm) and a fold-up eyecup. Bottom Line: A superb and compact top-class eyepiece. This is like binge watching 4 seasons of a great show with a total cliff-hanger at the end of season 4, only to have the network cancel the show. I am also intrigued by the 4mm. The only downside is that it's a bit bulky. They look very much alike the new TS UWANs, but with a special Stellarvue twist reminiscent of their 100 line. Make no mistake, these are large and heavy eyepieces, with some requiring 2-inch focusers. And if you like the UWANs, see my review of the WO XWA. New from Stellarvue, ultra-wide eyepieces. Note: For definitions of basic eyepiece characteristics mentioned below, see Ed Tings A Beginners Guide to Telescope Eyepieces. The failure rate, resolution, sharpness, and other subtle differences were there. It is been known for a long time that the 7mm UWAN is closer to 8mm, so maybe the previously given field stop specifications have been misrepresented so that the focal length-FOV equation should add up on paper(?). Good correction comes with a price.
