The Nagler 9 Type 6 is an expensive high-end eyepiece, and it performs like it. It takes a little effort just to see the field stop without turning my head, and the stars are very tight across the entire field in my f/6 Newt. Saturn hardly distorts even at the field stop. Contrast and sharpness are excellent, Ill need better seeing to tell if there is a difference between this and a 9mm Ortho I have. The only reason I dont give it a ten is that it would be nice to have a few more mm of eye relief.
