The retractable roof has been worked on so it no longer sticks from joint expansion. A new weather seal is installed, to relieve the problem. The First Aid kit is installed in the office. The new porch light is installed. The lightning arrestors and equipment ground strap are installed.
Wiring is begun on the emergency DC power system for the roof.
After focusing the telescope on Vega, we tested the resolution of the camera with this image of Epsilon Lyrae, a double-double star system. Since the pixels are 1.6 arcseconds across, we should have resolved the close binaries, but several factors prevented this, including very poor seeing. Instead we grabbed this image of a nearby starfield. Last, we snapped this image of Saturn. Again, the clouds prevented any more than an outline of the ringed planet.
