Hidden Mountain Observatory is open year-round, nightly with advance reservations for private star parties. The recommended start time is usually one, or two hours before sunset to allow time for setup of your equipment, if any. Obviously, suggested start times can vary according to the time of the year, but are flexible and can be adjusted, if desired.
Presentations about the night sky by a resident Astronomer may be requested at no additional charge and generally last sixty to ninety minutes. Observers with their own equipment are invited to utilize the site, with many level, grassy areas on which to set up. Those doing so are welcome to continue observing until dawn, if desired, and weather permitting. It is highly recommended that those doing so arrive before sunset to set up their equipment as the site is very dark, especially on moonless nights. All lights must have an appropriate red filter to preserve night vision for all guests.
There is a minimum of four (4) persons needed to book a party and, presently, all groups are limited to a maximum of sixteen participants on any given night due to the size limitations of the venue. Rates are subject to change and reservations are accepted up to one year in advance. You may change your date as often as you like without fees or penalties if weather is uncooperative on the date of your star party, or group function. All proceeds will go to help fund site improvements and future educational public programs. We appreciate your support!
