In addition to the usual point-and-shoot mode, the new camera is
designed to work in the
drift scan mode. The telescope is pointed at the sky but does not move
to counteract the
rotation of the Earth. Instead, various objects in the sky gradually
drift across the field of
view at the same rate as the computer records data from the CCDs, producing
photographs that are long strips of the sky. Astronomers will use these
photographic slices
of the sky to look for quasars, supernovae, asteroids and more.

This must be the ultimate version of the technique Tom Droege was
working on a few years ago.

Interesting reading and much more.

World's largest astronomical CCD camera installed on Palomar Observatory
telescope...

The Oschin Telescope had to undergo some major changes to accommodate the
QUEST camera...

*****

As would my Duplex Questar, no doubt. This camera is probably not for
me, but it sounds like just the ticket for the guy in sci.astro.amateur
who wants to buy a $750,000 amateur telescope...

I am not so sure about "ultimate," although that is not to denigrate
the project in any way. I'm sure it will do great things. The
technique, "TDI," is far from new, but that does not make it any less
valuable.

The plan is to have over 2 gigapixels. I don't think even this is
necessarily "ultimate."

"Ultimate" means "last", but not necessarily "the last ever".
