Hey folks! So I captured around 8hrs on Orion through L Enhance in my Bortle 9 yard with no moon at 60 seconds…..TONS of wonderful nebulosity but no blue, no purples and a blown out core. So tonight I’m grabbing another 2 hrs unfiltered at 15 seconds…..the trapezium is clear and clean in each frame. The question is what do I do now?……do I add this data to my existing and stack or do I stack it separately and treat each stacked image as a layer?
Orion Processing assistance?

You need two separately stacked images so they can be composited together via masking. Two layers with a mask in Photoshop would be straightforward.
You could go further and take a series of images at different exposures to bring out different levels of detail and color, then composite them all via layers with masks.

Thanks Dave! I’ll get tonight’s work stacked up tomorrow and follow up. The masking part is new to me but I am a photoshop user so I’m sure I can find a video or get some tips here.

60 seconds should not blow out the core https://www.astrobin.com/buqa5o/ . Picture was 90 sec subs
Allthough my red was limited too and the picture goes the blue...
The core wasn’t as bad as I thought once I went back before the stretches. I’ve got this stack, a fast stack unfiltered at 10 seconds and I’m gonna capture one more sequence at 120 seconds to stack so I’ll have three images to overlay
