So the best I can do is point at DEC 0 and HA -3
It will have to do.
I was of course assuming that your drift rate of 0.1% was using the raw sidereal rate and not a custom rate in APCC or any other model rate. Or are you saying that the drift rate of 0.1% is caused by your APCC model?

By chance we will have a clear night tonight (and near full moon) so I should be able to run the tests. To make sure, I assume you want APCC to not use the pointing model or any tracking corrections during these tests? I will do a plate solve at the start and end of each test (5 minutes). This will give me a precise measurement of the drift rates in both RA and DEC.
The third test is a problem though. The building the mount is located in does not permit observations below about 45 degrees. So the best I can do is point at DEC 0 and HA -3 .. is that okay?
