Stack in AA6 SP2

Post by Forum_2017 »

Hello

How to stack pictures that have different size and pixel size?
FYI; pictures issued from a DSLR and other from a CCD on the same target.

Thanks

Paddy

Hello, it's not possible (and you will not be able to correct the dark frame, stacking from different instruments). So, the solution is:

1) Preprocessing with DSRL images and its darks, to create the Master DSLR
2) Preprocessing with CCD images and its darks, to create the Master CCD.
3) Menu Image/Coregister to align one Master to the other.
4) Menu Arithmetic/Average to stack them (or Add)
