A preview for my work in progress on M 33 which I started working on.
This will be my biggest "project" so far.

This luminance stack consists of 1210 frames (!), which proved to be quite a challenge to process! Extremely fast hardware is required, in the end I managed to stack 1210 frames in "only" 3 hours but selecting them was a real pain. Both PI and APP had real issue with that many frames. But as they say, no pain no gain ;-).

Unfortunately the sky conditions where far from optimal some nights, but I have to do with it since we do not have many clear skies here in the Netherlands.

I did not do many processing on this stack, will save that for the final LRGB+Ha image ;-). Which will take allot of time for it to be completed.

I am quite happy with the result so far, the galaxy is there in its full glory it seems.
