Ernie,
Would you kindly elaborate on your statement about changing the DEC rate intentionally to diagnose tracking issues. How much do you change the rate, and what is it you look for in the resulting image? How long of an exposure would you take to see what it is you are uncovering?
Is there a way that I can find out if my PMX is tracking at the correct rate? If you look at the T-Point run I posted, and look at the polar alignment, is there any other reason why I should see so much trailing? If PE (which I have not measured yet due to my CCDSoft frustrations) is the cause would not my error be huge to do this in such a short interval (45 sec)?
I'm sorry for so many elementary questions!
Peter
