. Moore Observatory on the afternoon of February 27, 2007. This 185-degree fisheye view was recorded with a Nikon D70 and a Costal Optical Systems f/5.2 4.88 mm focal length lens. The roll roof building is in the center to the north, the RC24 dome is to the east on the right, and the CDK20 dome to the west on the left. Overhead the setting Sun is behind trees to the west, Venus visible here in the daytime is above the tree line near a contrail, and the Moon is rising over the RC24 dome to the east.
