Forgive the stupid question, I'm having a brain freeze. How do you register moon discs. Registax? I vaguely remember using it to align the sun during the Venus transit and the last moon partial eclipse but that was a while ago. Can't remember how I did it. I obviously need to save the registered frames as individual files. TIA.
hmmm, I think from memory; its the same as any planetary? make sure the alignpoints cover the circumference and cross your fingers. I would max up the 'working area' box (I can't recall the heading) in the tools too (not sure if its needed or not at this early stage but may as well). I often will need to crop when I have a zoomed region due to errors at the edge of frame but a disc I think you should be fairly ok.
I tend to use reg 5.1 and either use one big align box or several smaller multi align boxes. In general I find registax hit and miss on stacking Moon shots but if I have too many issues centring them in PIPP first tends to help.
