Tonight I imaged the Cocoon Nebula (IC5146) – a reflection / emission nebula in constellation Cygnus. The cluster is about 4,000 ly away. The seeing was great and the guiding with PHD worked perfectly well. I was a fantastic summer night.
For stacking I used DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping. The picture is also available in full resolution here.
