I'm going to have to go to a group dedicated to Kstars.
There is some documentation on supported hardware, but i need to find
people who have actually done it:

When I had access to a telescope, I was able to stitch something
together using my Nikon DSLR snapping pictures with gphoto.   But it
wasn't optimal because I had a very small Meade scope and the camera
was not weighted nor shaped to work in that situation.  I'd like to be
able to present a specific package of off-the-shelf hardware that
would work for backyard astronomy with a Fedora Astronomy image and
then start beating the drum to get other hardware supported upstream
in the kernel.   I'm sort of surprised that kstars doesn't support the
retail DSLR CCD cameras that gphoto does.

I'm in a situation now where I maybe helping a HS teacher put together
a robotic observatory. I want to give him the option of setting it up
using Fedora, and then giving his students livecds such that they can
control the system remotely. From reading the Kstars pages, it should
have the necessary bits to integrate the basics if I can find at least
one listed CCD that has native linux support, the Apogee USB units
listed may only need libusb and not a wacky kernel driver.
Everything else you want to control, like a filter wheel or even the
dome opening can be done via some simple DYI serial communications
scripts if need be (pyserial!!!!!)  But I don't want to DYI the scope
and the CCD if I can avoid it.  I'd like to be able to present Kstars
as the basic interface, since it saves captures as FITS files, when
can then be processes by any post-processor that understands FITS
