It's really quite annoying coz the object's so close to being in the EP and then there's this sudden final movement/ adjustment that takes it away from the FOV.
That'd be backlash, right?

Hi Matt
My Celestron Nexstar 5 does something like this, but on purpose it seems. It slews quickly to the object, slows down as it approaches, then overshoots slightly to rewind back to more or less central, taking out the backlash so it can then track correctly.
In my Vixen Skysensor 2000 GoTo unit, you can set the RA and DEC backlash parameters in the software. A low number “means” no backlash so the drive train drives at normal speed; a high number “means” lots of backlash, drive fast to take up the initial slack then slow down to normal speed.
Does you mount have any settings to adjust to take out the backlash? Either mechanically or via software?
Cheers
