Public Observing at the Robert A. Schommer Astronomical Observatory

Members of the Rutgers University community and the general public are invited to observe the night sky through the 20-inch optical telescope of the Robert A. Schommer Astronomical Observatory on the second and fourth Thursdays of every month, weather permitting. The observatory is open for two hours starting at 8:30 p.m. (October through March) or starting about one hour after sunset (April through September, when it is not yet dark at 8:30 p.m.).

Observing will be canceled for that night if the skies are cloudy at the beginning of the observing session. Please check this web-site for the most up-to-date information.

Scientific Highlights

Transit of Venus -- June 05, 2012


This image was taken at 08:03 p.m. EDT through a narrow gap in the clouds during the only few minutes that the transit was visible at the Schommer Observatory. The dark band in the lower-left corner of the image is the roof of the Pharmacy Building. The edge of the silhouette of Venus is ragged because of blurring by the Earth's atmosphere -- the Sun was only 3.3 degrees above the horizon. The 20-inch telescope was stopped down to a 4-inch aperture covered with a Baader solar filter. This single-color image was taken through an SBIG STL-11000M camera with a V-band (green) filter and an exposure time of 0.05 sec.


The Triangulum Galaxy, Messier 33 (M33)


This color image was created by combining three images taken through blue, green, and red (B-, V-, and R-band) images taken with the CCD camera on the 20-inch telescope of the Schommer Observatory.
