Hi Mark,
When I shoot stills I use RAW so I can modify WB, contrast, Picture Style etc later if need be. With these videos, you are effectively shooting jpg, ie you have to choose your settings in camera.
For my Jupiter, Mars and Saturn images I use:
Picture Style: Landscape (more vivid colours (but blue is enhanced), higher contrast)
Contrast: max
Sharpness: max
Saturation: max
These settings unfortunately maximise the noise as well, but that's what stacking is for. I have tried less aggressive settings but the resulting image ends up being more washed out. I believe the higher contrast compensates somewhat for the lower contrast in Newtonians.
ISO ends up being between ISO400 and ISO3200 depending on magnification/object brightness. Exposure is nearly always 1/30th sec (the longest) at 1920x1080 3x crop mode @ 30fps on the 600D. With my 550D I used the 640x480 video crop mode @ 60fps and 1/60th sec. the 600D gives you a wider image but less fps.
With Saturn and Jupiter I generally shoot 1min to avoid planetary blurring.
I've had no experience with a webcam, all I am used is attaching the camera to the telescope, selecting live view, focussing the image and taking the video. If I had to connect up a laptop etc I would be (as a personal thing) less likely to shoot as often.
Cheers,
Tom
