And yes...I prefer CCD for astronomy....although I still use film for
wide field imaging. Big chip cameras suitable for covering a wide FOV
and maintaining a favorable sampling ratio are still too
expensive...but they are getting cheaper. However I see the consumer
type big chip digital cameras like the Canons replacing the dedicated
CCD astronomy specific cameras for the average person in a short time.

Interesting thread to read through! Learned a lot!

Question: Now that Canon is using CMOS for it's digital battlewagons, given
your comment, it's worth asking what sort of performance CMOS arrays have,
as compared to both film and CCD.
