Description

Galaxy exposures, 16" F6.2 SCT, IRpass+RGB: 34x240sec+79x120sec+23x240sec

Subs/frames was calibrated with darks & flats.

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
