And of course your first light with the other eyepieces and the sweet SV80A (it's on my short list!). Teasing me? And it is just for 2-inch focusers and so requires 2-inch filters. I tested these on f/6 apo refractors and f/5 to f/6 Newtonian reflectors, concentrating on comparing on-axis and off-axis sharpness. Posted by Steve Lightstone on 8th Aug 2020. Heres a low-cost zoom eyepiece that actually works well. Kunming maybe? Bottom Line: Near-Ethos image quality for less money. I was surprised! . Pros: Low price; good eye relief; solid construction. 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. It was definitely one of the better ones, as the 24uwa/es82 is, and likely the exact same optics. The A-T 28UWA/StellarVue 82 and APM 30UFF has already been mentioned in this thread. 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. (2011) 1,348,335; (2021 est . Cons: Slightly soft off-axis performance. But the price is the highest. I love my 20mm 100 degree eyepiece. Alan Dyer is an astrophotographer and astronomy author based in Alberta, Canada. The apparent field is indeed noticeably wider than the other 82s. Honestly, I don't mind a 50-degree view, but 70 is definitely more immersive. First light: Williams Optics binoviewers - TheSkySearchers.com Eyepieces with 100 apparent fields of view provide the widest actual fields possible at any given focal length (with the exception of the few 110 and 120 models on offer). Maybe the following might help: This shows the FoV for a 28mm 82 deg, a 25mm plossl, and a 7mm Xcel EP on my Orion XT8 ( 203mm/1200mm = f5.9), Jon, I 'll be needing some guidance soon; the 28/82 is on the way: using that and my 7mm Xcel as a base, I'll be upgrading/replacing the others to flesh out a "good" set.

Another good example is the 50mm finderscope, from both WO and SV (I have both, mostly the same, both excellent). I present them in order of increasing price. They look very much alike the new TS UWANs, but with a special Stellarvue twist reminiscent of their 100 line. A best buy. 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(?). But the twist-up mechanism in one unit I tested (which I exchanged) was loose and rattled. Cons: Very aberrated off-axis star images; slightly less than 82 field. The eyepieces rival Televue but they were sold to fund an Ethos.I missed the 16mm and regretted it as it's a very useful focal length. They look as good to my eye as any of the other high-end eyepieces I've used. I'll have to change this in the upcoming 2017 Buyer's Guide. Pros: Best eye relief and off-axis star images. For me, I love 82 degrees, it feels just right. The true field of view is 0.75 degrees, with an exit pupil of about 1.9 mm. Will 1.25 inch eyepieces fit ES coma corrector? Night Sky Challenges and the Astronomical League. LMU - Ludwig-Maximilians-Universitt Mnchen, Macromedia University of Applied Sciences, Mediadesign University of Applied Sciences. The ergonomics of them is quite nice to me, fit the hand very well allowing for a good grip on them. There has always been a good OEM behind WO and SV, but the winner is the consumer, who quite frankly doesn't care because the consumer can't buy directly from the OEM. If so, you will need eyepieces with longer eye relief. Note the Meades middle-weight 638 gram mass and that both the Meade and Omegon are just for 2-inch focusers, requiring more costly 2-inch filters. Munich, German Mnchen, city, capital of Bavaria Land (state), southern Germany. For a lighter, lower-cost alternative, and for 1.25-inch focusers, you might wish to consider an 82 eyepiece. They're still well regarded, though the 28mm is said to be ergonomically awkward to view through. Some models sell for as much as $700 to $1,000 each. Click here to create one. While the 76 Baader Morpheus provides slightly less field of view than the rest, the long eye relief and excellent image quality makes it new favorite of mine, and worthy of consideration. Cons: Soft off-axis star images. Be informed, it can't hurt you. Anything is possible. That doesn't happen with 100 degree eyepieces. I've had both and they are excellent (and same price)! 8 & 10 Ethos has a bit more light transmission, but this EP is a fraction of the cost , and well worth it! 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.

Mega gratz on your new scope NIckwin. Please Log In to view the details for this classified ad. Toss-up, both a bargain @ $200. They make a good addition to the Stellaruve brandedplanetary eyepieces he has already been selling. I had the 15mm and it lasted 2 weeks in my case. I wouldn't expect additional focal lengths. Its smaller, lighter, and cheaper than the bigger ASIAir Plus astrophoto computer, but is it as good? I did sell a lot of axiom LXs though, and owned the 23mm for a while and was impressed with it. Thus my max AFOVs are; 2.5 is 45 degrees, 3.5 is 65, 4 is 45 degrees, 4.5 is 76 degrees, 5 and 5.2 are 65 degrees, 6.5 is 76 degrees, 7 and 8 are 65 degrees, 9 is 76 degrees, 10 is 70 degrees, 12 is 92 degrees, 13 is 65 degrees, 14 is 80 degrees, 15 is 62 degrees, 17 is 92 degrees, 18 is 62 degrees, 20 is 80 degrees, 22 is 82 degrees, 25 is 60 degrees, 26 is 62 degrees, 28 is 68 degrees, 30 is 80 degrees, 31 is 82 degrees, 34 is 68 degrees, 40 is 70 degrees, 55 is 50 degrees.

Edit: For clarification, I am referring to the apparent field of view of eyepieces, not the true field of view. However, the Omegon and Meade both have apparent fields closer to 90 as I measured it. This is the original 100 eyepiece and is still the standard of excellence. There are also 60 degree eyepieces like the Starguider ED and Paradigms.

Edited by 25585, 06 March 2023 - 09:04 AM. Have fun experimenting! 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. I've had a few of their scopes that are well made, and well corrected, but labeled as someone elses. Cons: Slightly soft off-axis performance. Theres a new alternative for the Celestron NexStar SE and NexStar Evolution series tripod a short, foldable tabletop tripod.

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. These wider fields allow me to see things with my peripheral vision and make the whole experience that much more comfortable and enjoyable. Below shows the 100 degree Ethos alongside the 82 degree Nagler. Fancy eyepieces are expensive, simpler eyepieces can be nearly as good and much more affordable. 3. But I prefer wider fields when possible - 82 to 100 degrees. Converted grades are calculated using the modified Bavarian formula, as stipulated by the resolution of the Kultusministerkonferenz (German PDF, 0,1MB). A year ago, they had 3 focal lengths of 82 eyepieces of 4, 7, and 16mm, and I reported them in the 2016 Guide to eyepieces. Why 5 stars?

So if you assign numerical values in ascending order starting with 1, the input for the grade conversion is as follows: In the conversion tool, you enter 1as maximum grade (corresponding to A+), and 5 asminimum passing grade (corresponding to D). I find there are very few choices when it comes choosing a high quality 70 to 82 AFOV design that have enough eye relief for me to see the entire FOV. But the original Ethos remains unmatched for optics. Both have the same true FOV and cover the cluster nicely. 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.
