Working With OSC Frames DeBayered Into Separate Color Channels
Hi all,
I'm just getting back into PixInsight processing
after about a 3 year layoff so I'm pretty rusty. Adam, your new
Quick-Star tutorials have been great for getting my "sea-legs" back
under me.

OSC Light frames into separate R, G, and Blue channels now that this is
offered as an option in WBPP and the separate DeBayer process.

raises some questions about the workflow steps that I'm not quite sure
about (for now I'm staying away from WBPP and running everything as
separate standalone processes to get back familiar with all the steps
again):

Questions:
---------------
1)
Is the main advantage of DeBayering OSC light frames into separate
color channel stacks to enable a higher quality Star Alignment process? Does this also make for a better DBE result too?

I'm using the SubFrameSelector Script and Blink as a backup to identify
my single best GREEN channel frame to Star Align the entire DeBayered stack as
one giant batch. Is this the correct way to go about Star Alignment?

3)
After Star Alignment has completed for the giant batch of all frames, I'm then re-segregating the files into their respective color channel stacks. Should I run the NormalizeScaleGradient script on each stack SEPARATELY at this point, prior to Image Integration?
