Hey bob bryant,

How many photos (roughly) were you attempting to stack? I've completed one of about 700 images which took 5 hours.

Can you tell me what format the images are and does it happen if you stack say, just 10?

Hi,

I also have frequent crashes of Affinity Photo 1.9.1 on macOS 10.15.7 on a 16" MacBook Pro when doing Astro Stacking. However, it may be that after crash and using the very same dataset Affinity runs through the process with success.

Happens for both CR3 (Canon RAW) and FITS as input.

In my setup, I usually run only one file group, containing at least lights, darks and bias. Sometimes also flats included. Crashes happen in all cases. The amount of data varies. Typically darks, bias and flats are 30 images each. For the lights mostly from 50 to 200. 

My impression is that the crash typically happens at the later stages of the process (progress bar beyond 50%). 

Please let me know what further information I can provide.
