Description

This is a four panel mosaic we have been working on this winter. Exposure time is about 3 hours per panel, all in broadband with no filters. We originally attempted this in late fall, but we took way too short of exposure times of 10 seconds in an attempt to better bring out the core of Orion, but it generated an incredible amount of noise. So we reshot earlier last month when we had an opportunity of several clear moonless nights with 60 second exposures in low-conversion gain (LCG) mode with extended full-well enabled.
