 NGC 7000, the North America Nebula

The North America Nebula

© Philipp Salzgeber

Film: Kodak Royal Gold 1000
Telescope/Lens: Nikon AF 80-200mm
Exposure: 2x10 min at f/2,8.
Date: 11 August 1997
Digital Enhancement: Stacking two negatives in PS

Comments: Some trailing of the stars is visible in this picture. Since it is absent in the other pictures, I think it is a result of the lens collar I use (Nicam 2,8) and the nearly vertical position of the lens/camera setup, in which the lens collar is obviously not rigid enough!
