Great image! I think I shall try your settings with my 600D, once I figure out how to do it.
Did you have to convert the video from MOV to AVI or does Registax 6 have no problem with MOV formats? Never tried it before as I use Lucam's SER format (Starshoot planetary camera) and I still use Registax 5. Being able to use my 600D for planetary imaging would save time in changing cameras and refocussing, etc.
