Recreational Vehicles/Camp Sites

There are no picnic tables, fire pits, or marked spaces in Camp Oakes. RV’s may not park on the telescope a field or in a way that will impede traffic or damage the environment at Camp Oakes. RV and trailer owners need to be especially careful of interior lights. Please park so that doors open away from observers, block windows to prevent light trespass, and mask interior lights with red cellophane as necessary. Generators may run only from 11:00 a.m. until 8:00 p.m. No RV’s are allowed to connect to the camp electrical system except at the Indian Guide Village!

Quiet Times/Active Locations

Not everybody sleeps at the same time. Many attendees will be observing from dusk until the wee hours of the morning. Please be courteous to your neighbors at all hours by minimizing noise. If you play music, play it quietly. On the other hand, please realize that your sleep may be disturbed by observers talking, using equipment, and in other ways as they stay up late. Locate your campsite accordingly.


When you leave, please make sure your area is trash free. Please leave Camp Oakes better than you found it.

Dusty Conditions

Outdoor carpeting under your scope and a tarp or other cover for the daytime are highly recommended to protect equipment from dust.
