I have a ten year old SCT.....Celestron 9.25. The stars at the edge (and considerably in from the edge) are a little fuzzier than I like.
I suppose I need a corrector. I have a corrector/reducer that gets it to 6.3, but want to retain the longer focal length.
Is there a good corrector that is appropriate for this?
