Hi,

I'm from portugal and I did not post here for a while!

I have a Tak FS102NSV fluorite Apo and a QSI532WS (KAF3200ME) that I use for photo and a small Tak FS60C and a QHY5 as a guiding system. Graeat combo, no problems with guiding, neither colimation and that stuff. But my passion is astrometry and photometry so my OTA needs to be a larger one. Since I never had other telescope other that APO refractors and I want to go with a much greater diameter I thought in a catadioptric tube (a SC or a RC). My question: what should I gain with a RC10" (GSO) over my small razor sharp Tak FS102 and what should I expect to loose? I have a almost new C11 from a UK astronomer waiting for me (?) but I don't know much about SC too!

Could someone help me please?

Regards,

paulo
