and the horsehead that you appear to have failed to mention...

Just out of interest, when do you sleep exactly? Do you have a hammock in the office?

What size is the CCD in that camera, the field is pretty wide for a 500mm lens.

Oh, and well done! You've gone and raised the bar again on the society's skill level, I think maybe some guerilla action on the electricity supply to your house should allow the rest of us to catch up :grin:

Ah. Right. Looks good. :wink:

Has anyone done any qantitative comparisons  of image resolution between webcam-type capture systems and custom astronomical image capture systems?

Just seemed to me that these images were really nice and crisp.
