Mission and Program Overview

Mission

To provide an opportunity for amateur astronomers and the general public to observe through telescopes and binoculars the dark night sky that is no longer available from most metropolitan areas in the United States.

Program Services

DescriptionGrantsExpenses
We hold an annual event in Central Oregon east of Prineville, OR. This event provides an opportunity for amateur astronomers to gather in a dark site location. With increasing amounts of light pollution, it is becoming more difficult to see the night sky. Most metropolitan areas have so much light pollution that this type of observing is not available. There are daytime activities such as speakers, telescope walkabout, youth activities, as well as the main activity of observing through some type of astronomical instrument. We operate under a US Forest Service permit on totally unimproved lands. We bring in 100% of all facilities such as our activities tent, registration tent, and portable toilets. This year had 301 registration from all over the Pacific NW as well as the rest of the country.-$35,339
