Adding additional Ha

[spillage]

Hi All,

I have currently added Ha,O,S 120s together but have some 240s Ha that I would also like to add. I normally do all my stacking in DSS first but what would be the best way and time to add the 240s Ha.

Cheers,

I was told by my mentor Ron Brecher that adding calibrated 120-180 and even 300s all together and then integrating is fine.   You can also take the 2 masters and copy them. then integrate those 4 files (after star aligning).
