Ditto to Doug's post on the gear. Why?
8" DOB - sets up in minutes and within most peoples budget
ED80 - portability, entry level for imaging, ok for terrestrial, and if game makes a nifty super telephoto
EQ6 - budget workhorse GEM able to take the weight if you expand (within limits of course) before moving on to something more expensive if need be.
DSLR - multi purpose beastie
Except for DSLR, all the above is dual-purpose imaging or visual. I can mount the 8" on the EQ6 for tracking/goto visual or videocam. I can mount the ED80 on a heavy duty tripod for quick grab and go.
...but that's just my 2 cents worth
