NGC7635 Bubble Nebula in NB

[powerlord]

Shot last night with asi1600 and C8. My asiair and EAF are refusing to autofocus reliably with Oiii and Sii filters even if I increase AF exposure, so shot AFed on Ha, then left for same for Oiii and Sii - which is why its a bit blurry.

10x180sec on each, with gain 139.

stacked then processed in Startools (binned 2)

oops just realised I didn't add my darks. with some 6d stuff (bias only) and others asi1600 it's easy to forget.

Will try to redo it.
