G'day Andrew
Setup > Statistics tells me version A3S5 ...
By concidence you're the second person today to explain the purpose behind training (i.e. backlash compensation) and that really helps understanding (thanks!).
Does it matter how tall the training target is. How about a mobile phone tower, and to get the elevation I set the telescope up say, 10 metres from the tower base, is that good choice? Should I move even closer, or maybe look for something much higher, a mountain side / cliff maybe ?
