ENR CTIO 1.5-m 2018-01-15

Date: 
Monday, January 15, 2018
Telescope: 
CTIO 1.5-m
Submitter: 
Rodrigo Hinojosa
Submitter Email:

Observer Support: 
None
Night Assistant: 
Rodrigo Hinojosa
Problems: 

When I changed the target from GJ1068 to UW CMa at 03:15 UT the telescope lost the pointing (I do not know why), I had to stop the observations to fix it.

 

I could check in the telescope that the shift in the pointing was only in RA. 

 

The finder in the telescope (red light cross) is not centered with the telescope, it has a shift to the east. I could center a bright star looking the guider screen with long exposures, a side of the guider screen was brighter than the other one, so I assumed that the star was in that side. 

 

The pointing was recovered at 04:12 UT.

 

Due to the lost of the pointing I could not observe UW CMa at 3-4 UT, which was a priority target for tonight program. I could not observe either the target HIP029810. The rest of the program was completed successfully.
