Problems: 

It seems when the telescope is pointing to an extreme position (HA>4) the CCD temperature reader goes wrong and shows temperatures much above normal (>100 or just out of range for the display, assumed > 200). Once the telescope is taken back to a zenith position, temperature shows normal values again (~60). 

We ran out of nitrogen when re-filling the dewar at midnight. Our friends from the 1.5m telescope help us to set up a new tank.

Comments: 

Smooth and productive night.

Dewar filled at 6:45am
