We have only a few rules for vistors:
The observatory houses a 6.25-inch, f/15 vintage Hastings-Byrne achromatic refractor, a 14-inch, research-grade, Celestron f/11 Schmidt-Cassegrain reflector and a Takahashi Dall-Kirkham Cassegrain reflector. The scopes are mounted on Bisque Paramount MEs, a completely automated control system that allows our operators to accurately point the telescopes at any celestial object includng the moon, planets, binary stars, nebulae, star clusters and galaxies.
In 2015, the club added a 5-inch Explorer apochromatic refractor with a Mallincam video camera to the Celestron scope. The color image from the camera is displayed on a computer monitor in the observatory.
The observatory building is a slide-roof design constructed by our members in 1978. It allows optimal viewing of the sky in any direction. Come early and watch us roll off the roof.
