Hey Han, I wanted to ask if you have plans to introduce multithreading for ASTAP, especially for Mac, in the near future. I read on the forum that you were considering implementing it, and I wanted to ask how this plan is progressing. Without multithreading, ASTAP stacking takes painfully long on Apple Silicon Macs. I stacked the Andromeda Galaxy with 400 pictures on a MacBook with an M1 Max chip, and it took nearly 10 hours.
