- The Observatory is not heated. Please dress for the weather.
The state-of-the-art Observatory features a research-grade, Classical-Cassegrain telescope housed within a six-meter retractable dome with a 20-inch mirror and is capable of viewing objects millions of light years away. The Observatory is operated by astronomers from Bergen Community College.
The telescope has several special filters designed to help minimize the effects of the area’s light pollution. The precision instrument also includes specialized cameras to photograph various astronomical objects, a photometer to measure the brightness of stars and study how they vary over time, and a spectroscope to analyze wavelengths of light to determine the chemical composition of light-emitting objects.
All ages are welcome and children must be accompanied by an adult. Twenty-five people may occupy the Observatory at any one time. Entry is on a first-come, first-serve basis.
