Question Single Star and Multi-star alignment data erase

From reading the manual, pp. 41-42, it seems that the mount does not retain Single Star alignment data when powered off. But the manual isn't clear about multi-star alignment data. In particular, it will usually be necessary to re-align if the mount is moved to a new location. This means that the old multi-star data must be erased. How do I erase the existing multi-star data so I can start a new multi-star alignment?

I did some experimentation (see my post on StarGo and CdC). What I found is that any multi-star alignment is erased when the mount is powered down and all programs are closed. If you want to save an alignment, you must save a file using the option on the StarGo control panel before closing it down. You can give it any name that you want in the filename box. It can be loaded the next time you start the program. As I explain in my other post, for all this to work you need to connect the computer to your mount by USB, and then connect the planetarium program to the mount in a wireless mode (I only tested Bluetooth because that's what I have, but I suspect that WiFi works the same).
