Description

Taken under a reasonably dark country sky from the backyard in a tiny franconian village called „End“.

Iso 6400.

No darks no flats no bias no autoguiding.

The Bresser AR-102xs/640 shows, due to its fast lens, significant blue chroma around brighter stars; however, this can easily be removed using the color replace tool in photoshop. It also shows significant field curvature; since I am not using a field flattener, I am concentrating on small objects centered in the optical axis cutting away the outer distorted areas.
