Description

SQ Galaxy subs was taken during 3 evenings/ nights in Oct-2021.

Subs/frames was calibrated with darks.

Decided to show this image as is, due to the astro-weather conditions in CPH DK turned bad again, at least for the next app. 10 days.

On purpose, the colors are shown very subtle :-)

As usual it's taken in a light polluted area, Bortle 6 sky looking south, Bortle 7 sky the other directions/ surroundings.
My home build observatory is placed in my front yard/in the "red light" pollution zone, have a look here,
Red Zone
Kind regards Niels
