The Class of 1951 Observatory

The Class of 1951 Observatory houses two large reflecting telescopes in separate domes: a 20-inch, and a 32-inch (one of the two largest research telescopes in New York State). Smaller telescopes include a Coronado solar telescope and an historic 8-inch refractor. Both large telescopes are equipped with research-grade electronic cameras, and three spectrographs are also available. All data acquisition and telescope control is performed from a large warm room. The observatory supports Vassar coursework, public education, and professional research in astronomy. Ongoing research programs monitor the brightness of potential planet-hosting stars to confirm or rule out the presence of exoplanets.
