Re: [APML] C 9.25 for AP?



I use a C9.25 on a G11 mount.  I would *NOT* recommend purchasing the focal
reducer for AP.  There is already vignetting without it.  With the reducer...
Well, I can't even find a guidestar with the STV.

So, if you are patient enough to work at f/10, it can be a great scope.  If you
want f/6.3, there may be better options...
