Tonight I finally got to test my C11 that I just put back together after a few mods. Slew to a few bright targets, focus, etc... all good... I use a Meade OAG with a prism. For the life of me, impossible to find a guide star anywhere.
Not to worry... I do unguided exposure 10-20s. all good. When I packed up, I quickly checked the OAG and saw that I put the prism back in the tube the other way round facing the CCD instead of the scope
