I bought the 16mm flat field eyepiece for my 6" Celestron Schmidt-Cass and it seems to work great. The field of view is decent but it's not expansive. I confess my observations with it have thus far (in my three weeks with it) been limited to Mars and the Moon. Because the Moon is the only edge-to-edge object I've seen through the eyepiece I'm limited in my observing experience. It looks great.
