Hello,
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.
Steve
