Problems: 

At 1:08 UT and anticipating that I was going to be observing a target a bit over 4 hours East in HA, I moved the telescope to a bright star at HA 3:50 all ok, then to HA 4:08  (DEC around -50 )I got the limits notification. Javier and Alvaro came to check, there is no clear reason why this is happening, maybe they can comment. So for the moment I wouldn’t venture going over 4h to the East.

Comments: 

Program not completed,  I skipped QR Pup and RKS1930-1523.

Ignore images 1116, 1163 and 1164, they are ThAr lamps that came out wrong.

Seeing data from RINGSS.
