This (portion of) M17 is a Work In Progress that I hope to update over time as I learn more processing with PixInsight. The aim is to make a decent image from the data using PI only.
I've got this data, taken with a STX8E:
Temp: -15
6 x 600sec Ha
6 x 600sec SII
6 x 600sec OIII
Darks: 12
No Flats or Bias
Eventually I'd like to mosaic the region, but for now, I'll just use this data.
This version is a beginning and I used PI for most of it with a final cleanup in PS.

In PI, I did:
* Made a master dark.
* BatchPreProcessing script to calibrate and register the images.
* ImageIntegration to create Ha, OIII and SII images from the calibrated, registered images.
* LRGBCombination on SII, Ha, OIII as R,G,B respectively.
* SCNR to reduce Green
* BackgroundNeutralization
* ColorCalibration
* MaskedStretch
* HistogramTransformation
* Deconvolution
* DynamicCrop
That's for this particular image. I did quite a lot of messing around with various Processes after the "ImageIntegration" above. My main focus with this first attempt was to try to get the colour right, which I did not succeed in doing yet. This means, for example, the stars need work (especially the 2 brightest ones). With my other attempts, I found I was often wrecking the colour balance significantly and getting magenta stars and/or washed out backgrounds, etc.
Now that I've had a good play with these processes (and more), I think I'll revisit the tutorials and videos to see what I should be doing - they might make more sense this time.
However, any hints, tips, etc would still be appreciated!
