Open Houses

Normally, members are at the observatory on clear weekends when there is no bright moon in the sky. Open houses, however, are scheduled events hosted by members. We might give a tour of the facility or a talk. We’ll try to introduce you to amateur astronomy and have plenty of handouts on how to get started.

If an open house is cloudy, it’s cancelled. A sign on our club house will indicate if the facility is closed.

If you wish to bring a group to an open house or schedule a special event, please contact us before the next regular meeting. Any such event would have to be discussed and approved ahead of time.
