I have spent the last several nights getting Ha data on M42. I will add color next new moon. This is a composite of 30, 60, 180, 300, 900 and 1200 second exposures for a total of 12 hours. I used a PixInsight tool called HDR Composition to get the Trapezium tuned in, I think this data looks good and should be great when I get some color in it.
