Since money isn't an obstacle, I would recommend getting a camera with a relatively large sensor. A small sensor means a small field of view which makes finding objects a pain. An ASI294 or 533 should do it. You wont need a cooled version, but you may as well get one. And although most newbies start out with a color cam (because, yeah, they want to see color), a mono cam is more sensitive and easier to use.
f4.9/1500mm fl (right?) needs precise tracking. So tracking is going to be your main problem. You can make your life much easier by reducing sub exposure times (increase optical "speed). Think a few seconds. That means a focal reducer. Unfortunately focal reducers are a bit of a crap shoot. The answer may be to contact this guy https://www.cloudyni...etup/?p=9298498 He runs a 12" Newt with a high quality ($) focal reducer/coma corrector (ASA) that does an excellent job. If he doesn't respond to a PM here on CN, he is a regular on the French forum http://www.astronomi...c.php?f=22&t=83
He is fluent in english, so language won't be a problem. Tell him I sent you.
Well, that should be enough to get you started on the right track. Any more questions?
