The XT8 is a fine scope, got one in 2001 & have no complaints.

There's a knob on the underside of the focuser on mine that adjusts how
easily the EP tube moves. Perhaps you have a different version though,
there are at least two versions of the pre computer assisted XT8 that have
different focusers (1 1/2" and 2"). I don't know what the 2" focuser looks
like, I suspect taht's what's described below.

The azimuth and altitude movements are fine, no complaints. The
focuser is fine, might could use just a tad tightening, but overall it
works smooth-feel no need to change the grease. I've went out with
this scope twice since I've had it, so it will put me through my paces
for a while.


Look closely at the focuser -- I may have a photo of this on my
collimation
page (which you have visited). On the focuser are two tiny Allen-head
screws -- I think it's 1.5mm Allen head. Tighten these to tighten the
focuser action.
