Hi,
If you have v6 of Maxim you can now image thru the meridian automatically. See here:

Maxim will also shut the scope/camera/dome down on weather/target too low/twilight etc triggers see:
http://cyanogen.com/help/maximdl/Setup_Tab.htm
This is useful for hands-off single object acquisition while sleeping!
If you want to periodically autofocus, acquire multiple objects without intervention, restart after a weather event, automatically do flats etc, you need more software (ACP, CCDcommander, CCDautopilot etc)
HTH,
