Yes I have sent Dave many PM's about high Quality eyepieces...and he has been great......Dave has already mentioned your Pentax range to me.....too bad we cant find much about the longer focal length Pentax's.....?
Short FL Pentax's get great review where the longer FL don't seem to get the good reviews......eg...2" 30mm & 40mm....something to do with the curvature?
