This is my first try at the North American nebula. This was captured in my backyard with bortle 7 skies so not great conditions. I used the astronomik UHC filter to try to isolate the nebulae more.
Gear:
Camera: unmodified canon eos 1200D
Lens: vintage asahi pentax 200mm lens f/4
Filter: Astronomik clip-in UHC filter
Mount: Star adventurer 1
Acquisition:
70 x 120s lights
25 flats and biases
Processing:
Still working on this but this is my current routine
Software: Siril + GraXpert
Manually stacked in Siril
Background extraction done to all lights before stacking
plate solving + spectrophotometry to get rid of green hue from UHC filter
Star removal
Denoising in GraXpert
Stretching in Siril
Stretching and saturation fix in stars (my lens causes a lot of chromatic aberration so this part sucks)
Star recomposition
Further stretching to tweak minor things
Veralux Vectra script is good for shifting the hues of the color palette to try to isolate the blue in the nebulae
Cosmic clarity sharpness script in Siril is good for trying to get small details and sharpening stars
