The scope knows what time & date it is between startups, and it assumes when started up that it's at 0,0.... I don't see why it'd need to have the date & time updated from a GPS or anything else?

I don't consider that it loses it's bearings as such, it just assumes it's at point 0,0 upon startup so if it's pointing at 0,0 accurately upon startup, it knows it's pointing in the right place..

It seems from discussion on the LX200 group that the concensus is my PC time and LX200 time don't match closely enough, or aren't accurate enough, or there is too much delay between me parking the scope at 0,0 and turning it off. I'm going to do some testing on those theories.
