Was shooting with this combo:

NINA 1.10 HF1 RC003 - Camera Set to RGGB

ASCOM 6.4 SP1
ASICamera ASCOM Driver 1.0.3.28
ZWO ASI Cameras Driver 3.0.0.7

 

After reading another thread about green stars, I updated my drivers to

ASICamera ASCOM Driver 1.0.4.5
ZWO ASI Cameras Driver 3.0.0.10

(I don't use ASICAP, but the other thread suggested using to to reset color - do I still need to do this?)

 

For all the images I just captured, can I balance out the Green and recover these images?

There are 2 files here, the raw fits and a demosaic version..

 

I tried changing up the matrix offset to 1:1 and the color control but nothing yet seems to get this back to balanced color.

Thoughts?

Thanks!

Don't understand your problem.  I just opened the file below in PixInsight and did an AutomaticBackgroundExtraction and the OK.  There was a lot of noise.

The recon file is unusually heavy in green and doesn't seem to have any red in the image... the colors seem wrong - even after the 'adjust color background' or 'auto color balance'...

Not yet. I need to put some more time in to eliminate variables... debayer matrix settings? Manual color balance? Etc.
When you ran the file and ABE, did the colors render correctly?
Thanks

Resolved! I set the matrix offset to 1,1 and after debayering, I ran auto color balance as the first step.
Thanks!

 Here's my result: 84 150sec frames, Gain 100, TEC -10, Bortle 6!

Running Auto Color Balance made the difference.

Thanks!
