1/ I hear a lot about ST80 refractors. what does the "ST" stand for? 2/ With a equatorial mount, once it is Dialed in properly, I would think that you could locate objects by going to the address. Sort of like a hand cranking "go-to" Am I right about that, or are they just for tracking with the turn of the earth? I've never had a EQ mount, and I live in a rural area, so my son and I make up the Astronomy club for our county. I wouldn't mind updating my refractor, and possible trying out this interesting mount.
