From time to time, my 1200 will have a lazy episode where it just won't

track.

The star will just drift away exactly like there's no power to the

mount.

Turning it off and on fixes this, but sometimes it takes turning it off

and on 3 or 4 times in a row. Then it's fine for the rest of the night.

What causes this?

No obvious reasons like overload lights or anything else is visible.

BTW, when it does track which is most of the time, it does a perfect

job.

What causes this? It's a little inconvenient.

What you need to do is remove the cover from the motor gearbox and look at

the motor shaft itself during this non-tracking event. Is the motor shaft

actually stopping during this time? If so, then there is something wrong with

the motor. Is the motor turning, but the scope is not moving? then we would

have to look further into the mechanicals.
