Refractors Reflectors Two Cats A few eyepieces
Quote:I think that the biggest problem with Pretoria sales was the 50° AFOV in the time of the 82° Naglers.I had the U/O 28mm and the Vernonscope 20mm. I thought they did really well, but I have gone to all refractors now, so they went bye-bye.Damnit! :-(-Chuck
Quote:Your Bertele looks like a 30mm to me adapted from a microscope eyepiece.Years ago, I owned an Intes 18mm Bertele eyepiece and it was pretty awful: strong yellow tone and ghosting. Not worth a cheap Plossl.Reality can be somewhat different from theory...

What some may view as an argument I view as a different perspective.
Quote:I would like to see a more modern Collins I3 like eyepiece, say in a wide-field or better yet; a zoom!
