NGC891 Galaxy from Paris


Here is the last image from my light-polluted backyard,  situated 20km from the Eiffel tower (Bortle 7).

NGC891 is a beautiful edge-on galaxy in Andromeda, in a background rich of distant galaxies.

I combined luminance data from a mono camera (ASI1600mm) with chrominance data from a color camera (ASI533MC).

200/800 custom carbon astrograph + 2.5" TS Wynne corrector on AZEQ6

OAG with ASI120 mini + ASIAIRv1

240*60sec with ASI533MC + L filter

180*60sec with ASI1600MM + L filter

Darks, flats, dark-flats and offsets

Annotated luminance:

thanks for looking,
