Reservoir Ridge
Fort Collins Natural Area
"Data collection effort to test the capability of the camera system to measure local glare by adjusting f/stop settings and exposure time. Very clear night, with only a little bit of dust in the air. Excellent transparency and the Milky Way is very visible (fairly good detail throughout) from the western horizon to about 20 degrees above the horizon in the east. M31 easily sighted. The light dome of Fort Collins and the rest of the Front Range cities down toward (and including) Denver dominate the sky to the SE and S. Local glare sources one mile away on the CSU campus are bright enough to saturate our image and effect scotopic vision."

"In clearing near spring creek trail north of the federal center buildings. Bright site with multiple glare sources. Attempted to block the brightest sources. No natural sky to observe, as light scatter was visible to zenith."
