Tweedledee Posted November 2, 2018 Share Posted November 2, 2018 Trying to lure me back from the dark side? ? Not that I've even got started yet. Very interesting eyepiece, but a bit of a straw to look through even in a 2.5" barrel. I've asked him to email some photos. Cheers Mick. ?

Tweedledee Posted November 6, 2018 Share Posted November 6, 2018 A quick calculation shows that when limited by a 2.5" barrel, a 100mm focal length eyepiece can't have an apparent FOV greater than 35 degrees. So it will definitely give narrow straw-like view. ? Link to comment Share on other sites More sharing options...
