Go to Google.com and do a search on "digital astro photography".
You'll find many websites with lists of equipment, techniques,
etc.
You can do some astrophotography very simply ... Some of the
best photographs I've seen of Haley's Comet from a few years ago
were captured using simply a DSLR with a 50-135mm lens mounted
on a tripod with a several minute long exposure.
If you want to use a telescope, you'll need a telescope adapter
and mounting tube, as well as a camera mount depending upon the
type of telescope you want to use. For any extended exposure
work, you'll need a properly set up equatorial mount.
One of the neater bits is that you can adapt Canon's excellent
TS80N3 wired remote and time unit to control a Pentax *istD/DS,
which gives you precisely timed exposures up to 999 hours when
using the Bulb setting, as well as intervalometer and extended
time delay functions. A bargain for its capabilities at $130,
and adapting it is simply a matter of cutting the cable and
wiring up a telephone stereo mini jack properly.
