I'm new to photometry. And I have some questions.

I can chose from an altazimuth mount with 68cm reflector or a 3600GTO astroPhysics with a tmb 130 SS

As detectors I can choose between

Canon 20Da, Canon 60Da, Stellacam 3 or an Sbig STL-6303E.

Which combination is the best?

Many thanks for your answers.
