Orion Ultrascopic 35mm
I rate this eyepiece a 10 for eyeglass wearers like myself. The eye relief is perfect. The view is sharp, with good contrast. I am currently using this eyepiece for low power, wide field views with my Orion Shorttube 80. The magnification is only 11x, and the field of view is almost 5 degrees. I highly recommend this eyepiece in combination with the Shorttube 80, especially for those who must wear glasses.

This has been my favorite low-power EP for years. The only caveat is that the eye relief is a bit long. I've gotten used to finding the sweet spot with no problem, but local light pollution becomes an issue if looking at galaxies, etc. Also it's a bit too long to use with my Mak (MK67) because the central obstruction interferes. Otherwise this is a dynamite EP and highly recommended.

This eyepiece has been a mixture of pleasure and annoyance for me. The views are great. Stars are sharp across the field most of the time in most scopes. Rarely, I will notice some minor coma at the extreme edge, but it could be related to certain scopes. The combination of perfect eye relief (for eyeglass wearers), large eye lens and good field of view give a widefield experience and very pleasant views. The eyepiece appears very well made - multicoated optics, blackened, baffled and threaded barrel, sharp field stop. Though large in size, it's really not heavy at all. The problem to look out for is that it requires far more in-focus travel than any eyepiece I've used. With a 2" diagonal and low profile 1.25" adapter, it will not focus in about half the scopes I've tried. If you stick to 1.25" accessories exclusively, this is a great low power eyepiece - perhaps the best in its format. I really like this eyepiece, but am continually frustrated by the inability to focus it in the configurations I prefer to use.

Excellent E.P. I have had this one for years, and it continues to be my favorite. Tack sharp images to the edge, ample eye relief, bright and clear. Highly recommended.

Highs: Bright, expansive (1.35deg viewing on 5"-f10 sct), flat views, good eye relief, sharp stop.
Lows: Tendency to blackout at other than center eye position - also a function of my pupil dia.
Overall: Significant improvement in terms of viewing quality over my Serious 40mm Plossl - the "looking through a pipe" effect is avoided. Give it a try, you may like it too!

This is my "go to" eyepiece for extended M-class objects (Messiers) and star fields. Pick one of these babies up until you can drop the 500+ dollars on a Panoptic or Nagler SWF. You may find you never need make the investment (or decide to add to your narrow band filter collection instead...)

Stars are pinpoints (but at 1 degree fields most good oculars provide "stellar" performance). Some coma at extreme edges. Bright contrasty images. Fine color.

Incidently, I also have the 25, 15 and 10mm Ultrascopics as well. At 120X the 15mm easily splits Epsilon Lyrae in my 150mm Argonaut on decent seeing nights. I also have the 25mm and 9mm Sirius Plossls. These perform well too - although they seem slightly less contrasty. (The Plossls came with the scope, and after evaluating them head to head with the Ultrascopics I would have done better to just use the Plossls at 25 and 10mm.)
