Description

NGC 6995 is a part of the well known Cygnus Loop, the beautiful supernova remnant. In 2018 I started a project to look for effects of expansion in my first narrowband images. The image from the eastern veil was a first attempt and I repeated the shot in 2019 with better exposure times (22.09.2019 Astronomik 6 nm OIII 24 x 300 s)

The complete bicolor-version is here

The Palomar Observatory Sky Surveys (POSS1 and POSS2) are one of the best source for good comparative photos.

Version A: animation 1989 / 2019

Version B: animation 1953 / 1989 / 2019 - with "dynamic distorsion correction" in Astro Pixel Processor
