Please adhere to the policies and Dark Site etiquette for night sky observing at the ‘O’Brien Dark Site’ since this location is in fairly dark skies. We need all those who are club members or invited guests to be aware of those who come out to enjoy a night of observing under the Stars! All information is available in the ‘members only’ section of the club website available to those who have updated their dues and membership.

There is no front gate the field is located to the right (West Side) of the property. There are no electrical outlets, so everything you bring that requires electricity will need to supply your own batteries and power units. The club’s storage unit is located near the fence on the far side of the field opposite to the road. O’Brien’s do provide restroom accommodations!
