Editing CR2 Astrophotography Files with DPP4 - Stars Lose Color

[MiGW]

Hello,

Shooting from very dark sky locations, using a star tracking mount, I get great results with extended duration exposures (60s, 90s, 120s, 150s), f/2.8 to f/5.6, ISO ranges from 3200-12800. 

My Rebel T5i pictures contained stars that were naturally colorful, orange, yellow, blue, white.

My 6D MkII pictures show colorful stars until DPP finishes drawing the image, then all star color becomes uniformly white. 

Is there some kind of in-camera pre-set that can be disabled? Canon Tech Support had no answers, had never encountered the issue, were unable to help troubleshooting.

Hopefully someone has a clue. 

Thx.

Hello Waddizzle,

Canon did not walk me through any settings checks. I use Landscape, shoot in RAW only, convert and save to JPG after editing for sharing. I will try all the Picture Style options and see if I get better results. I assume when I make a change it will result in adjustments that would have been applied if I used those alternative settings before shooting.

Regards,

Michael
