A revised version (with more integration time to reduce noise) of my previous image. A mosaic of Orion and objects North of it. Total field of view about 25x50 degrees. Taken with a Nikon 85mm f1.4 lens (at f/4), STL11K camera (at -30C), and Barr Associates 4nm Ha filter. Total exposure time about 15 hours. This mosaic includes several objects that I have tried in individual images, including: Barnards Loop, Sh 2-264, M1, the Rosette and Cone nebulae, Sh 2-240, and NGC 2174 and IC443, M35 and NGC 2158, M36, 37 & 38.
