I have some experience with deep sky imaging, but I had only a few tries at the moon.
As for optics I own a 6'' f/5 newt which I haven't used for imaging, because it's on a dob mount and it has no prime focus; 300mm FL old lens
which won't be of much use except on the moon maybe.
I also have 2 DSLRs, ASI 120mini, and eyepieces of very decent quality (x2 barlow, 26mm, 9mm).
I could start with a DSLR-Barlow-Newt for planets, but without the mount I think it'll be hard to guide by hand.
Using only my ASI 120mini and the Newt will give me very small FOV, so even worse. What do you suggest?
