apcc and refraction


Dave Goodyear <dave@...>
 

Hey Ray.



Not sure if you want this in the new support system. If so, let me know and
I will port it over.



My pointing model is 260 points (about 15 bad points) with a horizon limit
of 25degrees. I am using a THUM sensor.



Here are two test exposures of M5. Each 20min.



This first exposure is with pointing correction and tracking correction
enabled. Correct for refraction is OFF. Not bad, a few pixel trailing.
Refraction?

This second exposure is the same but with correct for refraction ON. As you
can see there is significant trailing.
