The full moon has given me some needed time to process some of my data. Next up in the processing timeline was M42. I collected this data about a month ago but the processing scared me given the large dynamic range of the object. Here's my first attempt at processing.
Details
Scope: 8" Newt
Mount: EQ6
Camera: Unmodded Canon 400D
Exposures: 12x300secs @ ISO800, 10x120secs @ ISO800, 10x30secs @ ISO800 and 10x10secs @ ISO800 plus darks and flats.
Stacked in DSS and processed in Photoshop CS3

I'm quite happy given that this is my first go. I had fun layer masking the core. Still need more data to increase SNR of fainter parts.
More than happy for anyone to provide any further processing advice or to have a go on the data yourself.
