Orion is the one of three targets I can image from my backyard.  I have been capturing it as and when opportunity presents in order to work on processing skills.

This was captured last week while sky was awash with moon glow. Had to keep exposures really short.

 

Canon 5d IV, 200mm f/2.8 lens @ 25 secs, ISO 320, 60 frames

 

I know lot of colors, how to process can be subjective however I would like to get some input from PI (or processing) experts as to what I could improve.

After calibration I applied these processes DBE, BNE, PCC,CT, ABE,HDR, LRGB combination,Range Selection and LocaHistogram to get above result.

That's a fine result considering the short exposure. With more time on target, you would have an outstanding image.

Can you post a calibrated, unprocessed .fit file?

Thanks, but that has been processed (stretched). I meant a stack that hasn't been debayered or processed all.

 

(I believe it would be in the .CR2 format for Canon.)

You want me to upload RAW files? There are about 60 of those.

If I upload a master light(integrated and calibrated lights) that was done using WBPP(all default settings)  will that do? That one is unprocessed.

That'll work! Just going to run it through Star Tools and see what we can get.

 

One thing I did notice when I converted the .xsif file is that you have  wicked gradient coming from the bottom left. Do you have light shining in? Was the Moon doing it's 'Ha Ha...I'm Here' thing?

Yes that red colored gradient. Oh yeah there was moon then there are few street lights & a traffic light.

 

Uploaded calibrated & integrated light

As mentioned earlier, your processing is fine and more integration time is needed, but still a good image. And no Moon or streetlight will help.

 

This is just a quick run with Star Tools. I cropped it down to save a little time and detail.
