I have recently processed images of Mars obtained in
I obtained the images with a Celestron 9.25 @ f/30 (with TV 3X Barlow), coupled afocally through a William Optics 40mm EP to my Sony TRV-900 3-ccd camcorder working at full optical zoom, for an image scale of about 6 pixels/arc-sec.

Thanks for your consideration,

The thing I have enjoyed the most in working with the Sony is it's ease of use and full manual controls, with shutter speeds down to 1/4 sec and independent control of gain. For the gas giants at large scale with the 6" MCT, this required exposures of 1/8 to 1/30 sec., at 6-9 dB gain. Locating objects is no problem using minimal zoom, which gives about a 1 degree field with the 6" scope, and a 40' field with the 9.25".
