Problems: 
One problem slewing to first target at handover. Brakes were preventing slew although target was not near any limits. It was only marginally windy. Lost just one image that was never delivered from SISPI.
Comments: 
Early start to community time to get field at 3:30, +14:47 while overhead. Tracking/guiding problems started immediately while close to meridian. Progressively tracking/guiding got MUCH better as target set. In the end guiding was some of the best I have seen this month while pointing north... at least it was not horrendous!
