Another good example is the 50mm finderscope, from both WO and SV (I have both, mostly the same, both excellent). I missed the 16mm and regretted it as it's a very useful focal length. Fancy eyepieces are expensive, simpler eyepieces can be nearly as good and much more affordable. When using hand driven alt-azimuth mounts this generous field will be appreciated. EPs: ES 2 . Have fun experimenting! Pros: Best eye relief and off-axis star images. I think these are the same that WO(?) Note: For definitions of basic eyepiece characteristics mentioned below, see Ed Tings A Beginners Guide to Telescope Eyepieces. I test ZWOs new ASIAir Mini. Its smaller, lighter, and cheaper than the bigger ASIAir Plus astrophoto computer, but is it as good? My conclusion upon testing this 100 group was that performance was more or less commensurate with price. The Explore 100 comes a very close second to Tele Vue in sharpness, with stars sharp across 90 percent of the field and still well contained at the edge. You currently have javascript disabled. Click here to simulate the field of view. How are the new Orion SkyQuest dobsonians? I've spent a decent amount of time with an 82-degree eyepiece, but the extra field never seemed very immersive to me. 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. MyGermanUniversity.com is Germany's largest database for English-language Bachelors and Masters programs (refers to degree programs with at least 50% English-taught course modules from German universities). The rubber eyecup can be raised higher with the use of an included extension ring; a twist-up mechanism would have been preferable. You probably won't notice the difference. I think you will find a wide range of preferences. 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.
Stellarvue EOP-09.0 Does anyone know anything about the new Stellarvue UWA's? In my 80/480 refractor, I find even 50 degrees for "high" power to be quite good--e.g., Nagler 3-6 zoom. Bottom Line: The best for optics but others provide more comfortable viewing. A 20mm eyepiece with a 100 field for only $300 seems too good to be true!
Eye relief is a comfortable 13mm and theres no annoying kidney-bean shadowing of the exit pupil, true of the others in this group. 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. Nuff said! They were identical to the UWANs (and 5 other brands of the same eyepieces). At a measured 13mm, eye relief seems a little tight, and 1.5mm less than specified, due to the eye lens being more deeply recessed than in the others. Maybe Vic star tests these though!
Telescope Eyepiece Kits | Shop Baader, Televue & Celestron Eyepieces In this complete system we include the large 28mm 2" wide field eyepiece for low power, the 8mm ultra-wide angle eyepiece for medium power, and for high power we provide the 4 mm ultra-wide angle eyepiece. Cons: Short eye relief and non-adjustable eyecup. But the soft eyecup nicely places your eye where it needs to be with no kidney-bean blackout. 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. 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. public University.

If the ones from Stellarvue also share these specs, then there is no doubt they come from the same assembly line. It is Bavaria's largest city and the third largest city in Germany (after Berlin and Hamburg). The A-T is darn close, but does give more magnification and FOV. I've had both and they are excellent (and same price)! 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. But it is an excellent eyepiece, for $80 less than the Tele Vue Ethos. It is important the image stays sharp as it crosses the field, and it does in both eyepieces, but the Ethos SX is better for double stars and planets.

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 saw clear, sharp, spacious views of Jupiter and the Moon when I first tried this eyepiece, and it also works well on double stars. Bottom Line: A superb and compact top-class eyepiece.
