"Star Parties" and Other Events


Our Star Party Workshops are held on scheduled Friday evenings in the summer at the Hidden Valley Observatory starting at dusk unless the sky is cloudy but normally not if the moon is too near to being full.  There is no charge for these public events, but donations are welcome.

All observing sessions are always contingent on the weather.  Click on the following link to check seeing conditions for the next 30 hours or so: Hidden Valley Observatory "Clear Sky Clock"
