IC 443 & NGC 2147
Went out to Spruce Mountain WV on spring break for a night and did 16 minutes of exposures on a bunch of different targets.
Stack Deets:
Equipment:
Camera - Sony A7iii
Lens - 135mm f/2 samyang @ f/2.8
Tripod - Bogen 3033 w/3047 head
Acquisition:
600x 1.6s exposures untracked, iso 52800
Flats: None
Darks: None
Bias: Used old bias frames from prev. exposures
Stack:
Siril - plate-solved all images and stacked w/ linear fit clipping
Processing:
BG extraction w/ graXpert
Spectrophotometric color calibration
VeraLux Hypermetric Stretch
StarNet star removal
Stretched starless a bit w/siril generalized hyperbolic stretch transform & adjusted black point
Star recomp
Cropped to square around interesting targets
Tried Syqon prism, and even paid for the deep model, it sucks balls. Not a fan, graxpert denoise looks better so I used that.
Working on building an OG Star Tracker but still need to buy the screws to get it all put-together.
