This was surprisingly hard to do.  I had to take then through my scope using the ASIAir camera control software.  The images are out of focus because my scope would not focus that close.   I put a green bucket, a blue bucket an a red snow shovel in front of them.  Hopefully they will be useful

The ASIAir software does specify RGGB in the FITS header.  The Canon camera is common and surely someone would have said something by now if this was wrong.
