Thanks for pointing this out. I visited the SBIG site, got the
relevant data on chip sizes and guiders, and added five cameras.
Download http://www.projectpluto.com/ccds.zip (about 12 KBytes)
and unZIP it in your Guide directory, and you'll see these added
to the CCD Frame list.

Please be warned that the guider chip is correctly sized, but
placement is a guess at this point. Also, I see that the new
cameras have _two_ guiding chips, the "traditional" one plus
one you can move around and put on a separate guide scope.
That way, if you're doing a filtered exposure, you can swap
to the other guiding chip set up on an unfiltered guide scope...
not a bad idea. I wonder if SBIG considered making a single
"movable guider" that could either nestle in next to the main
chip, or be moved to a scope of its own?

To handle the separate guiding chip properly, I'll have to add
something such as the ability to pick up the guiding chip and
move it... "management may work from sun to sun, but the
programmer's job is never done."
