About this image

 72 ED piggybacked to C9.25 on a CEM60 (using 9.25 for guiding) captured 12 subframes of 300 seconds each using my QHY168C one shot colour camera (cooled). Stacked nine of the twelve images in Deepskystacker including flat field subtraction but no darks used and processed using Photoshop CS2. Image is of whole FOV but reduced in size for posting.
