The North America Nebula and other nebulae in Cygnus.
20-minute exposure on Ektachrome Elite II 100 pushed 2 stops, using Meade broadband nebula filter, Sigma 90-mm f/2.8 lens, and Olympus OM-4T camera body. Slide was lightened by duplicating on Ektachrome 5071, then digitized with a Minolta QuickScan 35. Color balance and contrast were adjusted digitally. (Copyright 1998 Michael A. Covington.
