Is it possible to create a final stack with differing sub times and iso (having all cal frames for each sub set)? I.e. 2 integrations sets combined in the end into one image? I've got a feeling different times are ok, but iso won't mont mix.

Yes, one can! As a test I ran m45 subs from 2 nights, one set at ISO 1600@30 sec and the other set ISO 800 @ 60 seconds. Together they made up to 11,010 seconds, or ~3hr. little post in Lightroom and PS. I used the Batch modify tool to crop the best parts of the mosaic looking Integration so as not to have to do any work on that part.

And overprocessed with 12480 sec.

Trying to integrate 1,098 subs right now. 20, 30, 45 and 60 sec at iso 800 and 1600. APP is handling the task well, surprisingly well.

Hi Greg,

Yes, as you found out already, it's certainly possible.

One tip, if you combine data of different iso values and exposure times, it can be beneficial to change the normalization mode in 5) to multiply-scale instead of add-scale 😉

Kind regards,
