A wide field centered between NGC7000 and Deneb. M29 and M39 are included. Too short an exposure, as it was the first light (first track?) session of my Star Adventurer Mini and I took images of too many targets (including my first upload here:
Sagitta, Vulpecula ).
Camera settings: focal length 37.1 mm (full frame equivalent 100 mm), f:4.9, ISO 3200; high ISO noise correction on (rookie mistake).
The original version is the first one I then deemed half-decent. Preprocess: all fifteen lights, no bias or flats, forty darks with dark optimization, cosmetic correction (sigma 3, 3). Stacking: mean with rejection (winsorized sigma 3, 3). Postprocess: subtractive background extraction, green noise removal, photometric color calibration, color saturation increase, Asinh transformation, histogram transformation.
Version B is less overbright and has flats, so those two pesky fake dark nebulae to the north of the field are no more. There are now in their place, however, two slightly less pesky but equally fake faintly bright nebulae, so my flat processing is evidently... improvable.
