Problems:
There were issues with the telescope. Images near the zenith are elongated. We took ~30 minutes of exposures with this problem that are all bad. We spent ~1-1.5 hours trying to fix/diagnose this issue. We starting taking exposures at very high airmass 1.7-2 that seem to be ok.
In the second half we observed at airmass ~> 1.2. We did not experience problems.
