No need to replace scope & mount. Full view moon photo can be taken at 1/60s or faster. I think your setup is good enough for that. Have you turn on mirror lock? Wait about 10s after locking mirror. It helps minimize vibration during exposure. :D

You may try higher ISO and shorter exposure time.
By the way, can you show us your imaging equipments?
ISO already 3200 + exposure time 1/200 sec... :oops:

Then I would suggest use around ISO800 for lower noise. Even focus is not perfect, you may still use sharpening to get a reasonably good picture. Keep going!:wink:

Actually, quarter moon (as in these few days) is a better time for moon photo. Hills are more prominent with shadows. Full moon is just flat.
