Description

Hopefully during this month I can add more exposure time to this object, the weather conditions decide, not me ;-)

A IRpass-RGB color image & subs were taken during one night in March-2021.

Subs/frames was calibrated with darks & flats.

I have taken subs of this galaxy before, but first time with my new ZWO CMOS camera, just to see the difference.

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
