Comments: 

Just as it seemed we would forget what the stars look like, tonight it has been largely photometric over the parts of the sky that mattered.  Did Starflats, and Douglas Tucker's standards, then a pointing map, 6 exposures/pointing (not including round-the-pole) using new 4MAP and hexapod LUTs. 

Seeing not great and humidity hovering at 83-84% for several hours kept us on our toes.
