I have to disagree a bit. The Celestron Advanced Series CG-5GT mount is
capable of good GoTo performance, although it likely comes up short for
imaging with long focal lengths and unguided exposure times in excess of a
minute or so. That said, there has been limited success with these mounts
for imaging at short focal lengths (1000mm or less) where 30 second to 1
minute DSLR subframes at ISO 800 or 1600 are stacked through software.
One might want to consider this mount with an 8" SCT for both visual use and
imaging planets with a ToUcam at F25 or so, and then buy an inexpensive 6"
F5 (750mm focal length) for imaging nebula, large galaxies, and galaxy
groups with a DSLR.

Used these show up on www.astromart.com from time to time between $450 and
$600.
