This is the results of OSC imaging from dark skies (B2) last night. The night started with really clear air and the darkest I've seen for some time. It did fog up a little in the early morning.

I also have a new processing workflow, using APP for stacking, Siril for background extraction, photometric colour calibration and stretching, and adding the final touches in Gimp.

I used the best 75% of subs to exclude the foggy shots. This is 39x300s subs for a total of 3hrs 15mins.

SW 150PDS, ASI533MC Pro @ -15c/gain 100/offset 21. Baader UV/IR Cut filter attached.

HEQ5 Pro mount, TS-Optics 50mm guide scope, ASI120MM Mini guide cam.

Captured with NINA and PHD2.
