Choosing optimal reference frame for maximum overlap of all subs
Hi guys,
1) So have shot over 4 nights, same target, there is some rotation in the subs so im looking for a way to simply stack all the subs, then determine which single sub aligns 'the most' with all of the other subs and then use that as a reference image for registration & local normalisation. Is there a clever way?
2) Multi night imaging - avoiding rotation when you have to remove your imaging train from your scope... whats the best way to align this up before you start the imaging run so you can avoid the above?
