Requesting a Private Star Party Workshop

A star party workshop, far away from city lights

The Black Hills Astronomical Society has, as one of its missions, the dissemination of scientific knowledge concerning astronomy. To further this mission, BHAS offers “star party workshops” (observing sessions) at our Hidden Valley Observatory on selected Friday nights in the summer to which the public is invited, and also covers special astronomical events. A private workshop for a group may be possible at our observatory or at other locations if the following considerations are kept in mind.

Locations away from the observatory:  The viewing area should not be exposed to nearby lighting unless the lights can be, and will be, turned off. This also means that a location swept by the headlights of passing vehicles is not acceptable. The selected location must have a clear view of the sky, and an adequate area of flat ground to accommodate the participants and the required telescopes. Liability for any injuries or property damage at a location not under the control of the Society cannot be assumed by the Society. And if the participants are young children you must provide a sufficient number of adults for their supervision and to ensure their safety.

The proposed date(s) and time of the workshop should be selected with the reality of astronomical observations in mind. Nights when the Moon is full, or near full, are to be avoided as its light washes out a majority of the deep sky objects of interest. Outdoor activities are always subject to the possibility of adverse weather. Having an alternative date or program is a good idea as a successful workshop requires that weather conditions be mostly clear.

It’s important to note Star Party Workshops rely not only on BHAS members donating their time, expertise, and the use of their expensive equipment, but also includes equipment belonging to the Society as well as Hidden Valley Observatory, itself. To help offset observatory maintenance and equipment costs, the Society charges a modest support fee for private workshops. Any additional donation to the Society is gratefully accepted, as is any form of public acknowledgement of our efforts.

Payment and cancellation: The support fee may be paid in advance, or at the start of the workshop. If the event is canceled due to weather the fee will be refunded if it was paid in advance. If the requesting party cancels the workshop with less than 24 hours notice, however, the fee is still payable. In case of cancellation, rescheduling may or may not be possible and will have no priority.

To request a private star party workshop: Please contact us. All scheduling is done by the Observatory Director and requests are considered on a first come first served basis. The Black Hills Astronomical Society is a non profit, all volunteer organization, none of whom receive payment for their time or use of their equipment. As such, we are limited in the number of events that can be accommodated per season.
