Acquistion :
120x12s frames with a motorola edge 60 fusion using deepskycamera
ISO 1000 @ f1.8
Bortle 4/5 night sky
Processing :
preprocessed all dng's in rawtherapee
stacked the subs in sequator with freeze ground enabled
for the sky, BG extraction with graXpert, statistical stretch py script in siril, cosmic clarity sharpening py script and lot of manual adjustments in siril
was not satisfied with freeze ground performance of sequator so i used GIMP and from a single frame, using foreground select tool i cut out the building and replaced the building part in stacked image with it..
not well versed in GIMP so there are some artefacts
