Guiding Issues

Monday, October 16, 2017 1:55 PM

Problem(s) Encountered:

We experienced problems guiding on targets. Guider would freeze and stop guiding and occasionally the guide star would rapidly move.


We fixed the problem by changing the guide camera speed to 1MHz, exposure time to 1sec and aggressiveness to 6 in both x and y. The freezing of the guider may be solved by refreshing the guiding every half hour or so. This may not be necessary as this issue has not occurred for anyone else to this point.

The guiding accuracy with the new setting was quite good.

UPDATE:  New range extenders were installed in November.  So far, not freezing has been seen since.  That said, it takes many more data points to prove a problem is resolved than it does to prove it still exists..
