ENR CTIO Blanco 4-m 2016-05-21

Date: 
Friday, May 20, 2016
Telescope: 
CTIO Blanco 4-m
Submitter: 
Tim Abbott
Submitter Email:

Observer Support: 
Manuel Hernandez
Night Assistant: 
Alberto Alvarez
Also Present: 
Rodrigo Hernandez
Problems: 

The telescope does not like to make long slews.  4MAP crashed repeatedly when slewing to the eastern extremes of the round-pole pointing map.  A workaround was found by manually stepping to near the required pointing.  The tacos are freshly cleaned, so that's not the problem.

 

Comments: 

A crystal-clear night, used to complete last night's pointing map and to do a defocussed aberrations map with 8 exposures per pointing.
