Wonder if an aus-jena 4mm would be a good buy for a Questar? or for that matter, for any telescope.




Not for a Questar.

In other scopes? I had an original Zeiss Abbe 4mm. Not my favorite eyepiece. The Zeiss orthos are getting very nice from 6mm up, with the sweet spot in the 10 and 12.5mm. The longer focal lengths are superb too, but not your regular high-mag eyepieces unless you have a C14 or the likes.

A couple of years ago I had a set (16-10-6-4mm) ZAO IIs. The 16mm & 10mm worked great with my 3.5-inch Questar at 80x & 128x respectively. With the 6mm on the other hand (at 213x) the views were usually not steady enough (due to atmospheric turbulence) to warrant using it. I never even tried using the 4mm with it knowing the very high power it would yield (i.e., 320x) would not work well. I aslo didn't care very much for the 4mm Ortho because of its very short eye relief although I was very fond of the 10mm & 16mm ZAOs. I had the set for about 18 months and then ended up selling it for about 15% more than I paid for it.

While they were nice I didn't think that they were that much better than the Brandon and Tele Vue eyepieces I also had to warrant keeping almost 3K invested in that ZAO II set.

Thanks for the information about the eye relief.
