Stopped to move LBC-Blue hub down 1.00 mm (toward primary). Subtract 1.00 mm from PSF global offset.

Update AZEL WCS

07:22 - V5sec -- AZEL WCS now appears to be correct. Tonight's images earlier than this are incorrect.

Move to M92 for some science while we analyze our astigmatism data.

07:53 - M92_deepU_F2_2 - No focus update during the 10 minutes integration, and we still get 0.9 arcsec FWHM.

08:27 - M92_deepU_F2_3 - Telescope stops tracking during first dither near the end of the exposure. 0.85 arcsec at 1.1 airmass in Uspec.

09:02 - Vfastextra: -1073 -340 370 156 239 -108

09:05 - M92_deepU_F2_4 - Seeing gets much worse during third dither. 1.25 arcsec at 1.25 airmasses.

09:42 - M92_deepU_F2_5s (not the standard OB, 600 sec exposures are split into 3 x 200 sec; to test dither repeatability) Seeing is getting even worse, but then better again. Guiding failed on third image of second dither.
