Planetary Imaging Canon Custom White

[francis gerlach]

I have a modified T3i filter to extend the red range past Ha.
For normal imaging with BYEOS this works fine.
In the Planetary Video imaging mode the default does not use the custom white and the images are very red. There may be a way to select a custom white setting, but I have not found it in the menu's.  The other setting options such as daylight, tungten etc. do not correct the color balance.

Francis,

 

I do not have a modified camera...Yet...and I don't know if custom white balance is applied to LiveView frames or not.

 

In order to apply a custom white balance you first need to take an image of something that is pure white and fills the frame entirely.  That image needs to be in the camera and you need to specify it as the Custom White Balance image in the camera's menus (for my T5i the menu option is called "Custom White Balance" and it is on the 2nd [two dot] configuration menu). Then you need to select Custom from the White Balance (press the WB button) menu list. If this doesn't make sense, I am sure that the steps are in the camera's user manual.

 

If that does not apply the custom correction to the your planetary image, then you will have to correct the color balance manually in post processing. The brute force way is to align the black points of the three colors by looking at the histograms for R, G, & B.  Some programs may have color balance options that do the same thing.

CWB is not applied to live view frames; only the in-camera WB are <_>
