The Class of 1951 Observatory at Vassar College
in Poughkeepsie houses three telescopes: a 32-inch telescope (one of the two largest in New York State) for advanced courses and faculty-student research, a 20-inch teaching telescope, and an eight-inch refracting telescope for “naked-eye” observations. On clear Wednesday nights from 9pm to 11 pm during the school year, the observatory hosts “Open Nights,” when members of the community are encouraged to enjoy the natural beauty of the night sky. Targets of interest will vary between season and lunar phase. If the weather is questionable, contact the Department of Physics and Astronomy at (845) 437-7340 before 4:30 pm, or call the observatory at (845) 437-7679 after 8:45 pm.
