What Color is Jupiter
When I take planetary images I want to make good use of my camera's well capacity so I don't set the exposure time so low that the well capacity isn't well used  
I don't want to saturate any pixels so I don't set the exposure time too  high. I choose an exposure time (different for each filter) such that the brightest pixels
are about 80% to 85% of full well capacity
for each.

Since the brightest parts of a Jupiter image in each filter are the zones, that means for the brightest zones.I am choosing capture parameters such that

Red ADU = Green ADU = Blue ADU

I am making the zones white, but are they really? And how am I affecting the color of the rest of the image?

My filters have about the same QE one to the other, but my camera
(ASI174 MM with Sony IMX174 CMOS Sensor) has a lower QE in Blue than in Green  and
ower in Red than in Blue.

The confusing image below shows Camera QE for the camera used, the ASI 174MM (the camera with the higher QE at 500nm) superimposed on the pass
bands of the Astronomiks R,G,B and L filters.
Celestron C14, Televue 3x Barlow, ASI 174MM camera, Astronomiks R, G and B filters.

This is less processed than most of my images, but I didn't want to risk changing the color balance.

Do you think those are the colors you see at the eyepiece?
To try to calibrate the true R:G:B ratio, correcting for Camera QE, for differential atmospheric absorption and hopefully for everything else  I imaged several
stars at about  the same Alt as Jupiter, each star imaged with the same gain and exposure time  for the Red, Green and Blue filters. I then measured the total
ADU in the star image (less background). I used SIMBAD:


VizieR Online Data Catalog: Catalogue of Stellar Photometry in Johnson's 11-color system.

to determine the true B V and R magnitudes of those stars.
(My usual planetary imaging filters - Astronomiks R,G,B - are pretty close to the Sloan Cousins B V and R filters.)

I came up with a correction factor for each filter. I am a bit suspicious of the results, since they indicated I should multiply the V/Green value by 1.31 and the R
image by 2.05
which is more than the QE graph above would suggest, But I am correcting not just for camera QE but for the atmospheric scattering, for all glass
in the pathway etc. M
aybe that is accurate. Here is the result:
