Re: Stars drift with high resolution encoders

A tracking log will be a good tool.  You'll be able to see if it's servo position error for sure.
Do you have a video camera, or a fast cmos camera?  It would be really simple to make a video over time.  I would suggest the southern meridian for checking the azimuth, and east or west when checking the altitude.
Now you can see if it's interpolation error or not.

Hi Jesse,

Yes, that is an excellent point.  Use the Tracking log to see the numbers showing the motion of scope while tracking a target.
