I had a standard C11 and went to a C14HD. noticeable difference in flat field performance.? The C14 has some issues with focus and mirror flop so I would recommend using an OAG. I'm not sure if others have the same issue.?
The mirror?flop is an issue and I can't seem to resolve it. the mirror locks?help but engaging them changes focus enough to make a redo.?
The edge optics do not come into play if you use a hyperstar.? I have a C8 and a C9.25 I run with a hyperstar and use the C14 at F11 or F7 with an OAG.
