Description

2 nights before full moon, I thought this would be the best object to go for, due to its high signal. I really didn't want to use the L-extreme filter for M42, but without it the moonlight and neighborhood lights combined would have made it nearly impossible to get a decent image.

In addition to the longer exposures, 5 minute's worth of 30-second exposures were taken and used as a layer mask, to improve visibility of the Trapezium.
