Dobsonian mounts are alt-az, just like an
LX-200 without the wedge. So, you align the digital setting circles on the Dob the same as you do an LX-200, by pointing at 2 or 3 known stars. Then you can move the telescope by hand to the desired (RA, DEC). There are lots of digital options for Dobs like that. The
Orion Intelliscope series are SkyQuest Dobs with digital setting circles. You can also turn the Dob into an equatorial, in a manner of speaking, with a
split ring mount; they are not much harder to make than a regular Dob mount.
