I have a Nikon D7200. I tried shooting the moon last night using the back screen to focus with a 10X loupe. I think it is called Live View. The moon was so bright I could not see any detail to focus on. In addition, when using the loupe to focus, the texture of the screen is so pronounced, it is difficult to see detail of the subject (even when focusing on other objects besides the moon). I am open to ideas on how to use the back screen to focus.
When shooting the moon, I use full manual operation - shutter speed, aperture, ISO, focus, and camera mounted on a tripod.
An approach that has worked for me is to use Live View, with the 10X focus assist enlargement enabled so I can actually see what I am doing. Most of the time the in-focus indicator will turn to green.
If the moon is high in the sky, black field (no clouds or haze), for exposure I use an EV (exposure value) of 15, or the same as I would use shooting on a hazy sunny day around noon.
EV 15 translates to 1/125 at F16 at ISO 100. You can calculate the equivalent ISO, shutter speed and aperture for your particular situation.
Naturally the amount of moon being illuminated by the sun, sky and weather conditions, and the distance from the horizon are all variables that will affect your exposure settings. For example, a thin crescent moon near the horizon might only have an EV of minus 1.
This is a great guide for exposures of the moon in all of its phases:

D800, Sigma Sport 150-600, 1/200 sec, F8, ISO 100 (a little over EV 14 or so), tripod mounted.
