Description

Using a Canon DSLR for some years, I finally decided to invest into a cooled, monochrome CMOS camera. NGC281 is my first trial with the new gear and I am very pleased about what it can do for me.

Processing of the frames was made in Pixinsight, based on the very helpful video by Lefty’s Astrophotography, applying the EZ processing suit and StarNet++. No darks, flats or bias made. No dithering applied.

The halo around the brighter stars is originates from the H alpha frames.
