Saturn imaging attempt - Question

I was able to get one good steady 2 minute toucam video stream. Saturn seemed to process well. I cannot seem to avoid the blue/orange pattern on the edge of the planet. Is there an easy fix for this, or a change to the settings for the toucam. I am using a IR blocking filter, although it seems to do this regardless. Thanks.

Hi Tom,

Nice! Saturn , it looks like Saturn was below 45
degrees in altitude and you have some atmospheric dispersion
which produces the colors you ask about due to the color
channels not aligning correctly , you can correct most of
this by re-alinging the color channels during processing.
I re-alined your Saturn image and got rid of most of the
blue and red color , if you want I can post it here or send it to your email address , just let me know .

Thanks,

Wes Higgins

Tom,

Per your request I posted your Saturn image with
the color channels re-alinged , this removes most
but not all of the effects of atmospheric dispersion .
I did the re-alingment in Imagesplus .

Thanks,

Wes Higgins
