Hi Al, I'm wondering how I'll do that too

I'd imagine maxim would handle tracking sync between the dome and the scope via the obs control panel. I honestly haven't bothered to check it out yet. The dome driver I guess I'd use is only a trial and times out so I'd want something to trial it on first. At the moment it's all stop due to rain, I'm not game to plug any power tools in, everything is damp.
