About this image

A wider than normal view of the Crescent Nebula, NGC6888 (Sh2-105), associated with the Wolf-Rayet star WR136. The field extends south, past the faint Soap Bubble Nebula (PN Ju 1/PN G075.5+01.7), through areas of faint emission in both Ha and OIII, down to the small Cocoon-like Sh2-104 (DWB 14).

This was taken from EEYE in July 2021 (only just got round to processing!) on our shared rig, the image combining a straight RGB image with HA/OIII data (Ha in red, OIII Green, and OIII/Ha mix in Blue).
