Reworking the starry night sky with post-processing

Ideally in order to get proper astro shots of the night sky in it's proper accepted colors you'd have to modify the camera by getting rid of the infra red filters in the camera (within the filter layers of the "sensor" construct) according the resulting images more reds. Mode-ing the camera costs money and at the same will render the camera useless for shooting normal daylight pictures. It will affect autofocussing which means relying more live lcd focussing.

I have been meaning to modify my Canon 6D for a while now however kept balking due to in my mind unjustifiable cost it'll incur and consequential limited daytime use. So I tweaked the images in post processing instead trying out different post processing flow combinations.

These are the last few shots of the Milkyway made in Nov 2018 in Fidgeland. I retweaked these sample images from RAW files in CaptureOne:

WB 3250
Tint 1.4
Highlight 0%
Shadow 50-60%
Clarity 45
Structure 45
Luminosity 80
Detail 20
Color 80

these settings reveal slightly the remaining reds in these images. The images are then exported in JPG and tweaked again in Photoshop. Here I ADJUST COLOR and boost Saturation to +50.

It's obvious that the results do not  come close to images from a moded camera but it's close enough for me ... the red of Barnard's Loop is faintly visible in the last image near Orion's Nebula, I'm chuffed just for that. Looking forward to more night shots in the mountain when Milkyway season kicks up again.

Notes:
Barnard's Loop (catalogue designation Sh 2-276) is an emission nebula in the constellation of Orion. It is part of the Orion Molecular Cloud Complex which also contains the dark Horsehead and bright Orion nebulae. The loop takes the form of a large arc centered approximately on the Orion Nebula. The stars within the Orion Nebula are believed to be responsible for ionizing the loop. APOD April 2005 below by WH Wang (U of Hawaii).
