Inside Orion

Found this stacked Tiff file from a couple months ago that I didn't yet processed and seems I had forgotten it. Had some time yesterday to process the file so this is what I came up with.
Not sure how much subs the stack has but it was labeled "6 hours Orion ". If I remember correct it was a stack of 60-90-120 seconds exposures with a total of 6 hours.
I also used an extra hour of 30 seconds subs for the core of M42.
Camera was set at iso800 and lens aperture at f4 with a focal length of 185 or 200mm, can't quite remember.
