Well imaged.
Thanks Mike, the temp of the primary really is most critical. I never realized just how critical. The variations in quality from frame to frame in the animation were largely caused by periods where my primary went outside of the +- .5 C. Now that I have control of the temp it really is amazing to see the image quality vary over a relatively short time scale. Over the 100 minutes of this capture session the ambient steadily dropped and on a few occasions when I had turned off the Peltier's, the rate at which the ambient was falling meant that the temp differential became to much resulting in a rapid deterioration of the image. Turning the Peltier's back on rectified the problem in about 10 minutes.

PS – Nice stills too!
Thanks Dennis,
Yep a lot of time was involved, I am most pleased with how the RGB images turned out and by rapidly clicking between them the rotation of the planet and storm is most apparent. The rapid rotation of the planet really confines the length of time for the capture of the R, G & B channels. The shorter captures means a less smooth final image but the object was to resolve the storm.
