This is the current setup I'm using now. It's a 12.5" f/5.1 Newtonian. I usually use it with one of three coma corrector that I have. A Televue Paracorr, a Keller compressor/corrector, or a Lumicon coma corrector. I'm using an SBIG ST-4000XCM camera that I have come to enjoy.
The mount is an old Schaefer 12 that has been converted to a GoTo drive using Sidereal Technology motor controller and I am currently using Sitech software to run the scope.
