I was thinking about upgrading my digital imaging setup. I currently own a Canon T2i. I was checking pricing for refurb T7i's and noticed, along the way, that some of the ZWO cameras aren't that much more in cost. If I made the plunge, I would opt for a cooled camera. My scope is an R200SS/F4.
Is there an online tutorial about selecting a suitable camera? My primary interest is deep field, taking full advantage of the scope's fast F-ratio. Planets? Not so much.
I understand that larger sensors = more money.
Suggestions? What to read? Opinions?
