Harry Siebert Optics UltraPlus 20mm, 1.25 inch
I purchased a pair last spring to use in my binoviewer. At first I wasn't impressed with the "ajustable eyecup", which is just a snug-fitting metal tube over the eyepiece barrel assembly, set by an o-ring. It's imprecise and doesn't stay put. I set the eyecups in a preset position with superglue and removed the o-ring. Now I find them to be my favorite eyepieces for both binoviewing and single eyepiece. The view is indeed wide and very sharp. Eye reveif is very comfortable for me (no eyeglasses) with no backout problem at all.
