Description

This is the emission nebula Sh2-119 aka the Clamshell Nebula in Cygnus. Often overlooked, it’s only a few degrees away from the North America and Pelican nebula. Dimmer than its famous neighbors, it is still a huge and exciting target. Here I only have 4 hrs of Ha-OIII dual narrowband data from Bortle 7-8 skies and terrible seeing conditions. I didn’t get enough OIII signal to work out a good HOO-composite, but, despite the current imaging conditions here in KAUST (Saudi Arabia), with night temperatures of ≈30°C and more than 80% humidity, the result is better than expected 😉
