Imaging C27, NGC6888 Crescent Nebula

The Crescent Nebula located in the constellation Cygnus around 5000 light years away is my latest attempted capture.

For the post processing I decided to follow a tutorial by Celestial Photography (, and then also had a go myself.

This was captured using the Edge11, 0.7x reducer, ASI2600MC-P colour camera and a Baader UHC-S filter.

50 light frames of 120 seconds at a gain of 121 with the camera set to -5'C were stacked in DSS and then processed in Pixinsight.

Here is a quick accompanying video to the image:
