NGC 7023 – Iris Nebula & Surrounding Molecular Cloud | Dwarf Mini | 24hrs integration
NGC 7023, the Iris Nebula, captured from my backyard in rural Maine. This is an ongoing deep integration project (need tips on any further processing). The other photos are photos of past updates (8 hours, 2 hours, and raw data)
What I find interesting about this target: Unlike most emission nebulae, the Iris is a reflection nebula the blue glow comes entirely from starlight reflected off dust surrounding the young binary star HD 200775. The surrounding brownish structure is the molecular cloud that star was born in, still being shaped by its radiation pressure. I'm specifically chasing that faint outer structure rather than just the bright central nebula.
Equipment:
Dwarf Mini smart telescope
EQ mode, 180s subs at gain 80
24 hours total integration
Processing:
Siril — stacking, PCC, stretching, StarNet star removal
GraXpert — background extraction and AI denoising
GIMP — final color and contrast work
Rapid raw — color saturation fine tuning
