Hello everyone,

While observing the Moon for the Torricelli B TLP event with my LX200 10" last Thursday evening, I noticed what appears to be a slight jitter in tracking.

This occurred while in Alt-az mode. The scope was purchased last fall.

I first attributed it to atmospheric conditions but as I continued to pay attention to this, I noticed that it seemed to correspond to the tiny ticks of the RA and/or DEC stepper motors.

Observing again this past Saturday night I noticed the same thing, conditions much better this time, but still getting a bit if jittery tracking on occasion.
This is not something that I can noticed while observing deep-sky objects, and it doesn't occur all of the time. It is a bit annoying while performing lunar and planetary observations though and it may affect deep sky astrophotography, which I have not done with the LX200 yet.

Again, I'm very acquainted with the observational affects of the atmosphere and do not feel that this is the problem. My theory at this point is possibly a bit of play between the worm and worm wheels, or something along this line.

Anyone else experience this or have an explination or solution?

Thanks...
