Hi Lawrence,

If you have a "standard", off-the-shelf camera such
as an SBIG or MegaTek camera, you can just select your
type of camera. Guide already "knows" where the guider
chip is for these cameras, and will show it right away.
(Fortunately, this handles things for about 99% of the
world. Not many people are building their own cameras
with guiding chips! Those who do usually have to follow
the link Bernd mentioned, or just read the comments at
the bottom of the "ccds.nam" file.)

If you _do_ have a commercial camera that's not already
in Guide's list, please let me know, and I'll add it.
