Description

Sharpless Sh2-124 emission nebula lies embedded within distributed Ha and [OIII] nebulosity in the north-eastern part of Cygnus. It resembles a bit the Cocoon nebula some 4 degrees away, but without the reflection nebula part. It is a nice but seldomly imaged photographic target. The relative abundance of [OIII] in the G and B colour channels adds a distinct magenta-bluish hue to the otherwise red Ha nebulosity.

It took me 8 different nights in 2021 and 2022 to collect 25,5 hours of RGB, Ha and [OIII] data from my two extremely light polluted locations within the city centres of Vienna and Bucharest. Cameras used are AtikONE and ZWO ASI1600mm, imaging scopes are Skywatcher 130/650PDS and Lacerta optimised SW 200/800 imaging newton.
