This is my first attempt at a mosiac, there is about 4 hours of total integration spread across the panels, with M42 getting at least some from every panel set. There is a blend of 45s and 40s exposures through a CPC800 in alt/az at f6.3 with a Canon XSi at iso 1600. Flats, darks, and bias frames used. A "Paint" modification made to the upper left and bottom right corner, as internal reflections swamped those regions.
