The "go-to" camera/lens rig I have used for a long time is a D500 (which I use for the crop factor), 600mm f/4 ED-IF AIS Nikkor with Nikon TC-300 2x teleconverter. Including the crop factor, the total magnification is 36x (over full frame). A
very sturdy tripod is a must and either a corded or wireless remote release is strongly recommended. Wireless remotes are not expensive, I use one made by YouPro and it was around $22 on Ebay. If you don't have one you can always use the self timer. For support I use a Bogen 3040 tripod I got over 20 years ago. It is a
BEAST of a tripod at about 15 pounds including the head, but it is also rock solid. It is a very good idea to use Live View when shooting the moon. This is for a couple of reasons, focusing is easier as you can increase the magnification on the screen (my 600mm focuses past infinity as there are ED elements in it) and your mirror is already
up so you will not get vibrations (and therefore loss in sharpness) when the mirror goes up.
I took this photo of a waxing gibbous moon last night with the above rig right off the back deck. The image is essentially uncropped.
