There's nothing really special about it Bart, so nearly all main shelf planetarium software will drive both Meade and Celestron mounts. I know that my planetarium software of choice, Voyager, drives all CGE/CGEM and CGE Pro's natively. Prices range from free (Cartes Du Ciel, Stellarium et al.) to anything you like.

You didn't mention "Hallo northern sky" which despite the name works perfectly in the south, or "C2A" both of which work with any ASCOM compatible mount.
I should have stated "et al.", so I have. You're quite right Andrew - there are a few freebies out there that are worth looking at. I've run HNS (and found it pretty good actually) but had not heard of C2A. Looks basic, but I think that is because some developers take display screenshots of their software from low-resolution monitors for some reason.
