Thanks for all the input. All this has gotten me to thinking about security and equipment protection measures. If I leave everything setup, then I have the problem of leaving expensive equipment unattended. Since I don't live at my observatory site, there is a real problem of break-in's and theft, which is why I am right now making a complete list with serial numbers of all the equipment I have. There have been many threads on security and insurance, but now I had better take all that more seriously. I couldn't afford to replace everything, so I had better protect what I have.
