Re: Furthering the doom of astro CCDs...

Quick questions from someone who has little knowledge regarding
astronomical cameras. (The answers may not be quite so quick.)

What kind of pixel count is required (and available) for an
astronomical camera? (I know; depends on many factors, however an
approx value or range would be of interest.)

How does one deal with aliasing? Is this a problem for deep space
viewing?

When cooling a camera how is this managed without vibration problems?
Is liquid nitrogen used?

Do any DSLRs allowing binning for the three colors to give a
monochrome picture. If so, does this help much with the signal /
noise ratio? (It should help with the quantum noise if this is the
major noise factor for these cameras.)

A final question, unrelated to cameras, are there problems with
partial coherence (spatial) for viewing extended objects illuminated
by the sun and distant from the earth?

Lastly I apologize for asking questions I could probably find answers
for on the web.
