The image scale is too small, I need to about double my focal length. This was taken with a Intes PLUS MK91 9" f/13.6 Maksutov, operating at only about f/19 because I am still twiddling with my optical train. I need more space between my A-P Barcon lens cell and the camera... only getting about 1.3x coupld to a T-C thread adapter. But I digress.
I used a Supercircuits PC35C color 1/3" CCD camera, which has manual exposure/gain controls. I had the shutter speed set to 1/100 sec, and gain to auto. I used Registax to process 1000 frames to make this image, the best frames out of a segment of 1500 frames. I made a monochrome version and sharpened it in Maxim/CCD, then recombined it as the luminance channel in a LRGB stack with the color data. The PC35C has a low-light monochome mode (0.05 lux) which I will try using to collect luminance data next time, instead of faking it. Might make the C-ring show better.
I digitized the video live on site, no VCR or camcorder was used. I used the Dazzle Hollywood DV-Bridge to do this, plugging it into my laptop's Firewire port. I saved the DV format video to an external firewire-attached HDD of 120Gb capacity. This gives me a ridiculous 15+ hours of recording time (snicker). The really nice thing about this setup is that I get 29.97 fps with no dropped frames. For fast-rotating objects like Jupiter, the more frames in a short while the better, so I am really pleased with how well the DV-Bridge performs.
