Also the frame edge interferes with the view, cutting off bits.What I don't like about 'distortionless' or rectilinear eyepieces  such as in the Russian 7x30 and 10x42 is the sudden change towards the edge of bad angular magnification changes. Squashed full moons. And weird panning effects.I like 82 degree Naglers and the odd 90 degree eyepieces I have tried. I don't like a 100 degree Ethos.Horace Dall built a wide angle stereo camera based on Zeiss lenses that had 70 degree fields, as he thought this gave the best stereo photos. The stereo pairs were indeed very nice and better than most stereo pairs.</blockquote>
