What I dislike is decreasing the AFoV when increasing the magnification, the true field takes a double hit. The most eyepieces I use are 65 to 70 degrees. When using hand driven alt-azimuth mounts this generous field will be appreciated. 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. Pinpoint stars to the edge, M27 is amazing in my 14" Dobsonian. We all have different preferences for eyepieces. The Orion and Vixen 82 eyepieces are also superb in all aspects, though at prices similar to Tele Vue. 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. A 100 degree field of view provides the user with almost 1.5 times the area of an 82 degree eyepiece. Collecting EP's is a journey for sure in finding out what you really like. Does anyone know anything about the new Stellarvue UWA's? Nice wide field. The result given here is non-binding, as this grade converter can only provide a general first estimation. This 2 inch eyepiece is our widest field in the 82 degree range. The eye has to be a little above the eyecup for best position, with eye relief just 12mm. The Omegons weight is 600 grams, at the lower end of the range for eyepieces in this group. Cheers. Bottom Line: A good, economical choice for Schmidt-Cassegrains. I've pretty much settled on 68-72 degree eyepieces. Despite its size and dual barrel, its mass is only 586 grams, less than some of the competitors. Today, they report 4mm, 8mm, and 15mm and are $50 apiece less expensive, at $149 each. There are more expensive products, but do they perform any better? 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. 15mm Stellarvue is identical to the 14mm ES 82, field curvature and all, as noted above. Though advertised as 82, Celestrons 15mm Luminos had an apparent field between that of the 76 Morpheus and the other 82 models. Keep in mind, like appliances, or anything else, just because the OEM is the same, and they look the same on the outside, it doesn't mean they will always be the same on the inside. The latter had good optical performance, but with a twist-up eyecup mechanism that was stiff and greasy in the unit I tested. The 100 eyepiece tripod. Anything more than 82 would have me wasting time rolling my head seeing "what's out there" vs concentrating on what's in the center of the field. 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. You probably won't notice the difference. 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. Faster scopes (below f5.9) are more sensitive and require more expensive EP's and a probably a coma corrector. and even less can be tolerated in condition of tacking mount. Not quite so easy a question. Toss-up, both a bargain @ $200. Never occurred to me that they might actually be the same. Your scope is a f5.9. Our EOP eyepieces are now loaded into AstronomyTools database and application. Please Log In to view the details for this classified ad. Each of the eight elements are fully multi-coated, edge blackened and the lens barrel and baffles are similarly dark black. Old, from WO. This eyepiece gives me 133x mag in my 10 inch Dobsonian. A frequent example on here is the 84 degrees of the Docter 12.5, which is a highly accessible but wide field. But I can't confirm, and they could be a whole new OEM same as the luminos perhaps, rather than the initial SV82 which I am pretty sure was the UWAN. Your grading system is A+, A, B, C, D and E (Fail). It is plenty wide enough and 1.25 inch 82 degree eyepieces are just so much more compact than their 100 degree counterparts. Very fast shipping and packaging. The value for current overall gradeis the numerical value corresponding to your current overall letter grade. 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. However, stars began to bloat 60 percent out from the center and were quite distorted at the edge. The grades represent the following assessments of the examination performances: Talent Development, Scholarships and Awards, Verification of Study Periods for Pension Insurance, Mission Statement and Teaching Constitution, TUM Center for Digital Leadership Development, Digital Programs of Executive and Professional Education, Office of the Senior Executive Vice President, TUMonline TUMs campus management portal, Academic and Examination Regulations (FPSO), resolution of the Kultusministerkonferenz, 1.01.5 very good: excellent performance, 1.62.5 good: performance well above average, 2.63,5 satisfactory: average performance, 3.64.0 sufficient: performance meets the standards in spite of deficiencies, from 4.1 fail: performance does not meet the standards because of substantial deficiencies. Joining an astronomy club can also put more eyepieces in your focuser to the test. The 28mm has a 2" barrel, the rest are 1.25". I briefly experimented with a 100-degree eyepiece but it felt exactly like the 82-degree field, with the exception of shorter eye relief. We are fast approaching "galaxy" season, with the planets in the rear view mirror. Teasing me? With the 20 mm I will then have 32, 20, 16 and 10 mm equivalents. Either model represents an excellent value in a mega-wide eyepiece. All of these factors add up to create an extremely contrasty eyepiece that is free of unwanted reflections, flaring or ghosting. Thanks! Edited by timmbottoni, 03 November 2014 - 08:49 PM. Bottom Line: The best for optics but others provide more comfortable viewing. It is likely KUO like the WP Meade UWA, who also make the UWAN/PWA. But its the design and optical ease of a design that makes an eyepiece good for me. Tight eye relief, a lot of field curvature, and edge-of-field brightening at f/10. 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. You will get more use out of middle and low magnification EP's now. Have fun experimenting! The result is the equivalent to your grade in the German grading system, where 1.0 is the maximum grade and 4.0 the minimum passing grade. 3. It was definitely one of the better ones, as the 24uwa/es82 is, and likely the exact same optics. 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). While still impressive, they arent as wide as the others. Pros: Very comfortable eye relief; superb optics. If the grading system of your university uses letter grades, you can assign a number to each letter grade. Will 1.25 inch eyepieces fit ES coma corrector? He (or his expertly trained staff)machines optical tubes and adapters, polishes lenses, fabricates altazmounts, and yes his triple testing of his refractorsis now legendary! The new PWA has an improved design with a standard fold-up rubber eyecup and good eye relief. Good luck and clear skies! Now if you had a more expensive 30mm EP, that FOV will remain sharper to the edge. Probably not by much, if at all. Those look just like the WO UWANs, and they are in the exact same focal lengths. It is Bavaria's largest city and the third largest city in Germany (after Berlin and Hamburg). I am also intrigued by the 4mm. But I prefer wider fields when possible - 82 to 100 degrees. No question they set the standard. Bottom Line: A superb and compact top-class eyepiece. Guess I never answered the OP's real question here - favorite FOV, lol. Click here to create one. When I decided that I wasn't agreeing with an eyepiece, I sold it back on the used market for what I paid for it. Effect of barlows / field flatness for AT60ED solar imaging. The eyepiece offers a generous 15 mm of eye relief and has a standard foldable rubber eye cup. I find I kind of have to make myself use them more often. The new TS UWANs are waterproof and filled with nitrogen. This affect is more pronounced in lower magnification, wide-field EP's. It's the same at low power, which Ernest just pointed out. This is a recommended complete set of eyepieces for use with any Stellarvue telescope from the SV70T to the SV152 Flagship! The tool will then calculate your grade in the German grading system. 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. The specifications state an 86 apparent field but it appeared to be the same as the other 82 models. Like the Ethos, it can be used as either a 2-inch or 1.25-inch eyepiece. MSRP $350. In the AD8, the APM delivers tack-sharp stars to the edge. This is why some wide field EP's cost more, some, a lot more. The only cons I've noticed is that they are big and heavy and change the balance point for my small scope+cheap mount and like any other optical system they have to cool down to ambient temp to get the best view (which takes a few minutes). Because they're Stellarvue! Edited by Someone4322, 06 March 2023 - 03:36 AM. display: none !important; Bottom Line: A top-class eyepiece for optics and build quality. A 20mm eyepiece with a 100 field for only $300 seems too good to be true! The A-T 28UWA/StellarVue 82 and APM 30UFF has already been mentioned in this thread. Those I find are easiest to use. Do you search for top universities and information on admission requirements, language certificates (TOEFL/IELTS) and application deadlines? For a differentiated assessment of the examination performances, the grades can be increased or decreased by 0.3 to intermediate values; the grades 0.7 and 5.3 are excluded. 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. On the 2-inch focusers on my Newtonians I had to pull the eyepiece out a little in the draw tube to have it reach focus. At TUM, grades from 1 to 5 are assigned. 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. (Yeah, yeah, I know that's asking a lot.). Report back witn with your thoughts when you get a chance. Has anyone out there tried both or have any thoughts? I did sell a lot of axiom LXs though, and owned the 23mm for a while and was impressed with it. Not to say that normal 50 and wide-field 65 eyepieces arent excellent, but for a more immersive viewing experience most telescope owners add at least one, if not several ultra-wide 82 eyepieces to their collection. The eyepieces rival Televue but they were sold to fund an Ethos. Heres a low-cost zoom eyepiece that actually works well. In my 80/480 refractor, I find even 50 degrees for "high" power to be quite good--e.g., Nagler 3-6 zoom. Waiting Period: We are in continuous production and operate one year in advance. Most suffer from variable plossl, svbony, SVBONY Zoom Eyepiece, Zoom eyepiece. I am fortunate that I do not need to wear glasses.. Over the years, I have built up a collection of eyepieces that includes multiple sets. But I'm thinking a pair of the 16's might make a nice selection for binoviewers. Bottom Line: A superb eyepiece for 2-inch focusers. Academic Ranking of World Universities (ARWU) #48, Academic Ranking of World Universities (ARWU) #52, private (state-approved) University of Applied Sciences, View all 231 courses still open for next intake, Marketing services for German Universities. I think they are made by the same company that made other brands, Orion, Zhumell, SmartAstronomy, et al. All of this experimenting made me settle on 70 as a nice middle ground. Super crisp images to the edges. The ergonomics of them is quite nice to me, fit the hand very well allowing for a good grip on them. With some help from the members here, I'm awaiting a 28mm 82 degree Stellarview EP. Seeing the outer 10 degrees in direct vision is not so easily done. Going Wide: Nine 82-Degree Eyepieces Compared, A Beginners Guide to Telescope Eyepieces, Price and Quality in a High-Power Zoom: SVBONY 3mm-8mm Zoom Review, Celestron Tabletop Tripod Review: Sometimes Smaller is Better. 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. Just teasing you, David. I think you will find a wide range of preferences. The 4 and the 8mm have barlow lenses in them and they are the same eyepiece other than the barlow lens. I would target a 12mm-13mm for my first EP purchase. Stars begin to distort in the outer 25 percent of the field, so worse than the Explore Scientific and Tele Vue Ethos, but still very good, especially for the price. I didn't understand how big a deal this was until I bit the bullet and purchased a chair. But once i start using something around 1m+ in focal length, I find 70+ degrees is preferable, and if it matches nicely with the scope, the more apparent field the merrier. His website at www.amazingsky.com has galleries of his images, plus links to his product review blog posts, video tutorials, and ebooks on astrophotography. The only cost I had to eat was shipping, but spending $20 to rent an eyepiece is worth it to me. The rarity and significance of O-type stars brighter than 6.55 magnitude. My conclusion from testing this 82 group was that the Explore Scientific came very close to matching the standard-setting premium Tele Vue Nagler, but at a lower price. ***Apparent Field of View measured in degrees. STELLARVUE OPTIMUS 20MM 100deg 2.0" 9-ELEMENT EYEPIECE Description Technical Specs Extended Information Stellarvue Optimus 20mm 100deg 2" 9-element eyepiece--lighter and sharper than its competition, this eyepiece redefines "wide" field.

At under $200 this eyepiece is a great way to get those wide views at a reasonable price. Accessories, Astrophotography gear, Reviews. Anyone know who makes the StellarVue Planetary eyepieces? The TeleVue eyepieces are very sharp across the field, the Astro-Tech eyepieces slightly less so but they provide essentially the same views, just not quite so perfect. You sometimes feel more like you are actually there, in the view. The 13mm Televue Ethos is $658, the Televue 13mm Nagler is $335. Cons: Slightly soft off-axis performance. I find that the longer the focal length of the scope, the more I wanted wider apparent fields. Stars are sharp across all but the outer 10 to 15 percent of the field, so very close to Nagler performance. Going Wider: Five 100-Degree Eyepieces Compared, A Beginners Guide to Telescope Eyepieces, Price and Quality in a High-Power Zoom: SVBONY 3mm-8mm Zoom Review, Celestron Tabletop Tripod Review: Sometimes Smaller is Better. Other than that, this eyepiece is excellent and certainly merits your consideration. Thanks for any input if anyone is still watching here.

The one piece of information I have not been able to find here or on other forums is what FOVs people prefer, whether the specified field of view is at specific focal lengths or in general. They look absolutely identical apart from a few superficial features (eyecup, 1.25" barrel and rubber grip band). That's easier with the smaller size of the 82 Naglers when compared to the 100 eyepieces, however I'm working on that. There's also a comfort factor. Program Fees: 0 - 10,000 (per semester) Academic Ranking of World Universities (ARWU) #48, QS World University . 8 & 10 Ethos has a bit more light transmission, but this EP is a fraction of the cost , and well worth it!
