Description

My 2nd try at M42 - The Great Orion Nebula.

This time, I collected over 2 hours of imaging data, in a clear night of (relatively) low humidity.

The use of a Bahtinov mask helped me achieve much better focus as well.

As evidence to this, many satellite trails were caught passing in front of Orion during the session.

Unguided, no coma corrector used.

Revision 1: Additional 1.5 hours of data included in the new revision. The total data is now ~ 3.5 hours.

Revision 2: Tried a different, much more organized workflow, that is less aggressive with each individual tweak.
