Oh - for that you just connect the focuser and then go to the control panel and select the tab for Focus
There you have a choice of 4 buttons to push. You either press In:Fine or Out:Fine - or you can press In: Coarse or Out: Coarse
The number of steps moved for a fine or coarse move can be set in that display - and you press the Fine or Coarse button with a direction of either In or Out.
