Status report from Rochester





  I have now verified that the RA drive does work properly: last night,
for the first time, I took images with the RA drive running at the
sidereal rate, and they indeed show little trailing. Rah! 

  Last night was the coldest night of the season so far: the temperatures
dropped below freezing as soon as the Sun disappeared below the
horizon. I discovered that the water/antifreeze mixture I use to cool the
cameras had frozen. Actually, only the portion of the liquid in the
small section of tubing which is exposed to outside air (between the
garbage can and the shed) was actually frozen. I managed to thaw out
that section by pouring warm water over the tubing. When I finished
using the camera, I connected the two ends of the exposed tubing
together, and kept the pump running. This morning, I verified that the
fluid was still running freely. I guess I ought to add some more
antifreeze. ...
