North America Nebula
This is a stack of 32 exposures, i.e. 53 minutes in total plus 13 dark-frames. The camera (Sony ILCE7) and the 200mm lens (Canon EF 70-200mm 1:4L) have been attached to a "Star Adventurer"-mount in order to compensate for earth rotation, while shooting at F4.0/ISO 1600. Stacking has been done with DeepSkyStacker, and final editing with Photoshop CC 2015.5. Place of observation was close to Bremen, in the northern part of Germany.
