Problems: 

Telescope misbehaved tonight. I attempted to take it to HA=5:15 and DEC -52:30 within the limits but the telescope reached the limits anyway. It took me about 30 minutes to get it back as it would not move except with the set option. 
Afterwards, I tested with a bright star at HA=04:05 and DEC = -44:00 and again it reached the limits when it was well within the tabulated values. 
Could someone take a look? We have some targets that need to be observed within certain time windows and not being able to trust the telescope’s limits is very troublesome.

 

Comments: 

Program completed.

TIC79403459: First and second observations one after the other. Because of the problem with telescope limits tonight, I couldn’t take the first one before, and all targets in between were already observed. However both observations are within the given time windows, namely  @ 8:04 UT,  8:26 UT. The third was @ 9:48UT.
