Description

This nebula is just a little north of my previous image of CTB 1 (Abell 85) Supernova Remnant.

This is a Ha image processed to bring out as much faint nebulosity as possible and still produce a nice contrasty, sharp image.

Imaged over 5 nights from 16 - 20th Sept 2019 under Bortle 8 skies with an average SQM-L of 18.41 (averaged nightly readings of 18.3 - 18.55)
