Oh, barlowed the 15mm starts to show curvature around the 80-85% mark for my eye and the 4 and the 8mm the same since already barlowed. EPs: ES 2 . and even less can be tolerated in condition of tacking mount. I think they are made by the same company that made other brands, Orion, Zhumell, SmartAstronomy, et al. I don't know how much help my opinion will be but I will certainly share what I can when I have them in front of me. Joining an astronomy club can also put more eyepieces in your focuser to the test. As for "triple testing" eyepieces, that I seriously doubt happens. Favorite eyepiece field of view - Eyepieces - Cloudy Nights I am also intrigued by the 4mm. While the NexStar SE/Evolution Celestron, Celestron Tabletop Tripod, NexStar SE. This is why some wide field EP's cost more, some, a lot more. Though more costly, the Stellarvue Optimus also stood out for price vs. performance in a full 100 eyepiece. I test ZWOs new ASIAir Mini. Cheers. The jump from 50 to 70 provides a much larger leap than 70 to 100 to my eyes. You currently have javascript disabled. The latter had good optical performance, but with a twist-up eyecup mechanism that was stiff and greasy in the unit I tested. The knurled grip rings and construction of both are superb. This particular line saw its sales creamed by the superior ES 82s when the price on the latter was reduced. On my f/5 to f/6 test scopes, stars started to distort 50 percent out from the center and were quite bloated at the edge, the poorest optical performance of the group, but one thats commensurate with price. i think that what you are going to hear is : "what are you interested in looking at ?" They made their own products as well. But it just matters on if you need the eye relief or not, the AT UWA 28 would be great as well if not wearing glasses. 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. 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. 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). Old, from WO. In the case of the old JOC days, the axiom LX 15mm was probably the same as the 14mm UWA. Maybe Vic star tests these though! It is plenty wide enough and 1.25 inch 82 degree eyepieces are just so much more compact than their 100 degree counterparts. See William Paolinis review of all six Morpheus eyepieces here, and his full review of the Morpheus 17.5mm eyepiece here. Today, they report 4mm, 8mm, and 15mm and are $50 apiece less expensive, at $149 each. For low power, large FOV, I recommend you limit the eyepiece focal length to ~35 mm (thus a 7 mm exit pupil.) 70 is fine at low power, 78-85 fine at medium power, but I prefer 110 at high power. They look as good to my eye as any of the other high-end eyepieces I've used. Please note: Internationally, grading systems used at institutions of higher educations may differ substantially. For a lighter, lower-cost alternative, and for 1.25-inch focusers, you might wish to consider an 82 eyepiece. Cons: Very aberrated off-axis star images; slightly less than 82 field. How are the new Orion SkyQuest dobsonians? Do you search for top universities and information on admission requirements, language certificates (TOEFL/IELTS) and application deadlines? So from a practical point of view, I find there's little difference in drift time. Those look just like the WO UWANs, and they are in the exact same focal lengths. Another good example is the 50mm finderscope, from both WO and SV (I have both, mostly the same, both excellent). I once read that Televue actually bench tests all of their eyepieces before delivery to their customers or dealers; if so they may be unique in this regard. The main drawback is the massive 833 gram weight, by far the highest of the 100s. As such, the Nagler Type 6s are showing their age, as newer models of eyepieces, including Tele Vues own Delos series, provide adjustable eyecups and much longer eye relief, important for us aging observers! Don, I know the FS size controls the AFOV, but I thought the F/L was inherent to the optical design? I figured out my preferred fov and eye relief by purchasing used eyepieces here on CN. Other than that, this eyepiece is excellent and certainly merits your consideration. I just purchased a SV80A (really excited) and they had deal going where you get the 8mm and 15mm for a little over $100 so I jumped on it. If so, you will need eyepieces with longer eye relief. That makes swapping eyepieces at high magnifications easier. Introducing the new Stellarvue Ultra Wide Angle eyepiece series. any limitations are just limitations and can not be named "favorite", (2) acceptable (not a favorite) eyepiece AFOV depends from nature of observing object. I knew they were re-branded. Astronomy Clubs, Star Parties, Shows, & Conferences, Community Forum Software by IP.BoardLicensed to: Cloudy Nights. I like having eyepieces at my fingertips. Eye relief is a comfortable 13mm and theres no annoying kidney-bean shadowing of the exit pupil, true of the others in this group. 82 Degree Ultra Wide Angle Eyepieces - Stellarvue 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. 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. The failure rate, resolution, sharpness, and other subtle differences were there. It comes with a pouch with a belt clip. Though advertised as 80, I found the apparent field matched a Naglers 82 field. Please note that this tool is only intended to provide a first orientation and the results are in no way binding. Below shows the 100 degree Ethos alongside the 82 degree Nagler. That is a beast and my first 2 eyepiece. I started with the A-T and would still have it if my wife did not wear glasses (I'm guessing it's only a matter of time for me as well). I see only two, a 9mm and a 6mm. It's all part of the marketing game. Which points out that the appropriate high power apparent field depends a lot on the focal length of the scope and whether the scope is tracking. These are $65 or so.., Observing in Northern/Southern Michigan, USA, The NEAF Report from nPAE Precision Astro Engineering. 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! Based on the 14mm SSW, I can recommended the series, though they are even more costly than Nagler Type 6s. For 1.25" 82 eyepieces, I have a mixed set of Televue, ES, and UWA. New from SV? I do most of my observing with 82 degree eyepieces. A great one-two punch when observing. They make a good addition to the Stellaruve brandedplanetary eyepieces he has already been selling. Both have the same true FOV and cover the cluster nicely. Bottom Line: A top-class eyepiece for optics and build quality. Vixens fine eyepieces dont get the respect they deserve. Its smaller, lighter, and cheaper than the bigger ASIAir Plus astrophoto computer, but is it as good? Like the Ethos, it can be used as either a 2-inch or 1.25-inch eyepiece. It is just on the edge of being sensitive to what EP you can throw in the focuser and get good results. Have fun experimenting! The 13mm Televue Ethos is $658, the Televue 13mm Nagler is $335. There are more expensive products, but do they perform any better? LMU - Ludwig-Maximilians-Universitt Mnchen, Macromedia University of Applied Sciences, Mediadesign University of Applied Sciences. Theres a new alternative for the Celestron NexStar SE and NexStar Evolution series tripod a short, foldable tabletop tripod. But yea I mainly like using EP's in the 70 - 82o FOV range. The ergonomics of them is quite nice to me, fit the hand very well allowing for a good grip on them. Cons: Field less than others; eyecup height not easily adjustable. Grade Conversion Formula for Grades Earned Outside Germany - TUM 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. Now I see all 3 at half price sale for under $300 for them and that's pretty good, imo! Notice how it's sharp in the center and as you get to the edge the stars grow tails? *Measured with eye cup rolled down. Are these made by United Optical? He sells a 4.9mm and a 6.1mm, I also have his 2.9mm which seems to have been dropped from the lineup. You probably won't notice the difference. Munich | Germany, History, Population, Oktoberfest, Map, & Facts Bottom Line: A well-made eyepiece but costly for the performance. Hmmm, looks like those four focal lengths are the only ones they make, at least for now. I need at least 22mm of effective eye relief. At least I think they are new because I can't find anything about these focal lengths, they currently have 4, 8, and 15mm available. I recently purchased the 9 mm Optimus eyepiece after my excellent experience with the 20 mm Optimus. Program Fees: 0 - 10,000 (per semester) Academic Ranking of World Universities (ARWU) #48, QS World University . 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. 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. Bottom Line: A superb eyepiece for 2-inch focusers. Enter the maximum grade, the minimum passing grade, and your current overall grade in the grading system of your university. Its long 20mm of eye relief, screw-up eyecup and large eye lens makes Orions Lanthanum a pleasure to use. I tested several eyepieces advertised as having 100 fields, all with focal lengths from 13mm to 15mm, a good sweet spot for any eyepiece on most telescopes, and encompassing the focal length of the original 13mm Nagler and Ethos models from Tele Vue.
