I have the chance to acquire a second-hand G3-16200 with an external filter wheel with 7 positions. I think it is the Mark I class 2 version. Although I like astrophotography I would like to use it for photometric work mostly.
So, my questions are: how is the camera behaviour in photometric work? It is linear enough to make good work for supernovae, comets, asteroids, exoplanets, etc photometry, of course being aware of its linear range?
I would like to find someone with this camera using it for this kind of things and get his/her impressions on the matter. I've done some research on the web with no results.
Thank you so much in advance.
