The dates of our public Friday Night Star Parties, and our regular meetings, are available: Click here for schedule information

Friday nights that are too close to the full moon are avoided.   Please note that star parties are held "weather permitting". Click on this link for weather information: "Clear Sky Clock"
A star party is cancelled if the weather is rainy or cloudy. We usually begin each summer star party starting at about 9:00 P.M. 

We may be able to host a group for private viewing of the heavens using our facilities.  However, to arrange this please contact our observatory director (see "Questions?" below) up to 3 months, but not less than 2 months, in advance to reserve a date.

Our star parties for the public are a great way to learn about astronomy and see things for yourself.  In order that they be enjoyable for everyone, we ask that you familiarize yourself with star party etiquette (click here).

The Hidden Valley Observatory is located at 4715 Hidden Valley Rd., about 1/4 mile west of Sturgis Rd. (Hwy 79 north).
