The Best Times for Stargazing in Coos Bay
For the best experience, target the late-night window between 1 AM and 4 AM in Coos Bay. This is when local industrial lighting and residential 'sky glow' is at its minimum, and the most prominent Winter constellations are directly overhead at the zenith.
Expert Tips for Coos Bay Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Coos Bay, looking slightly to the side of a faint nebula will reveal much more detail than looking directly at it, especially when dealing with the Class 5+ suburban skies of the OR region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 3 at Hillman Peak (108.1 miles away) remains the benchmark for regional sky quality.

Hillman Peak
Crater Lake NP
Local Relevance
For observers in Coos Bay, Hillman Peak serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Site on summit of Hillman Peak, highest point on Crater Lake Rim, small area to set up instrument. Seeing very good transparency good. Fire smoke in many quadrants in the distance may obscure sky glow from distant cities."
Cloudcap Point
Crater Lake NP
Local Relevance
For observers in Coos Bay, Cloudcap Point serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Moderate winds with occasoinal gusts, combined with high humidity caused some unsteadiness. Otherwise a very clear night. Only small light domes directly visible, with Klamath Falls and ??? Being slightly obscured by cliffs and trees. Fine detail visible in Milky Way, including Prancing Horse near Saggitarius. SQM: 21.47 (1st), 21.41, (2nd), 21.44 (3rd). ZLM of 6.7 in Lyra. Brightening on horizon to SW is a light dome, not the Milky Way, but is obscured by cliffs. I believe a hint of airglow was visually noticeable."
