The observatory's telescopes can be used for both research and public viewing. The observatory is open to the public only during scheduled Open House events.

The latest addition to our collection is a Planewave CDK 700 27-inch telescope. Images are captured by an Andor Ikon-L CCD in addition to a Takahashi Petzval refractor. The telescope is housed inside of a clamshell, AstroHaven dome. This telescope is located next to the original dome which houses a Meade 16-inch LX200 Schmidt-Cassegrain with an attached 5-inch Televue refractor.

Each telescope uses special CCD cameras to image faint astronomical objects. The cameras pick up details that the eye is unable to detect. The cameras can also collect data for long periods of time while tracking the motion of the stars in order to capture detail.
