Plumas Lake
Stargazing Guide.
Just 41.4 miles from the center of Plumas Lake, lies some of the region's best viewing at Community Observatory. We feature instrumented readings from Buckhorn Group Camp to guarantee the most accurate sky quality data.
Stargazing Logistics for Plumas Lake
- STEP 1. Primary Staging Area: Community Observatory. This is your most reliable community-vetted hub within a ~41.4 mile radius.
- STEP 2. Sky Quality Baseline: Classified as Class B (Rural). Use the instrumented 4 rating from Buckhorn Group Camp as your technical benchmark for the region.
- STEP 3. Local Support: Contact Sacramento Valley Astronomical Society for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Plumas Lake offering varied horizons and atmospheric stability levels.
Plumas Lake is positioned in a strategic 'Starlight Corridor.' It is far enough from the CA metro glare to allow for deep-sky imaging, yet serves as a convenient staging area for the deeper Class 4 skies found at Buckhorn Group Camp.
The Best Times for Stargazing in Plumas Lake
Observation in Plumas Lake is most rewarding during the Summer months. During this time, the colder air masses over the Pacific region often result in significantly higher transparency, allowing you to see objects like the Andromeda Galaxy or Orion Nebula with much more definition.
Expert Tips for Plumas Lake Observers
If you're visiting Community Observatory, bring a pack of chemical hand-warmers and rubber-band them to your eyepiece or camera lens. This acts as a 'budget' dew heater, which is essential for the humid nights often found in CA during the peak viewing seasons. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Buckhorn Group Camp (71.8 miles away) remains the benchmark for regional sky quality.
Best Spots for Stargazing in Plumas Lake
The most accessible and reliable viewing locations in the region, ranked by local observer feedback. Max out your local session by using the essential observer gear staged for the Plumas Lake environment.
Community Observatory
" Heading out from Plumas Lake toward this location will reward you with steady horizons. Veteran Pro-Tip: Avoid using your phone's white screen. Even with low brightness, it resets your eye's Rhodopsin levels instantly. "
Folsom Powerhouse State Historic Park
" Heading out from Plumas Lake toward this location will reward you with steady horizons. Atmospheric Tip: Scintillation (star twinkling) is a sign of high-altitude turbulence. If stars are twinkling heavily, stick to low-magnification wide views. "
Mount Diablo - Lower Summit Parking Lot
" For the dedicated Plumas Lake observer, this spot offers a superior escape from light pollution. Participate in hands-on astronomy activities followed by supervised observing through the many different telescopes of MDAS members. Bring snacks, water, binoculars, and warm clothes. "
Museum of Science and Curiosity (MOSAC)
" Heading out from Plumas Lake toward this location will reward you with steady horizons. Atmospheric Tip: Scintillation (star twinkling) is a sign of high-altitude turbulence. If stars are twinkling heavily, stick to low-magnification wide views. "
Aerospace Museum of California
" Plumas Lake observers often find this mid-distance site perfect for a full session. Scientific Fact: Around 3 AM, the atmosphere is usually most stable, offering the 'steadiest seeing' for high-magnification planetary views. "

Buckhorn Group Camp
Black Butte Lake RA
Local Relevance
Plumas Lake enthusiasts typically use the instrumented readings from Buckhorn Group Camp to calibrate their deep-sky expectations for the area.
"Northeast through south along the horizon has numerous bright light domes, the brightest of which definitely affects dark adaptation. Early evening sky is much brighter overhead than late, presumably because of outdoor lights being shut off, but airglow decrease also a factor. By early morning, the light domes are seen to extend to less than 45 degrees above the horizon, while in early evening to at least 60 degrees, with only a small area near the zenith lacking a distinct brightness gradient. SQM 21.44 at 9:30 PM (Sales), 21.77 (Duriscoe) 12:30 AM LMT."
State Line Lookout
Lake Tahoe Basin
Local Relevance
Plumas Lake enthusiasts typically use the instrumented readings from State Line Lookout to calibrate their deep-sky expectations for the area.
"Site of old State Line Fire Lookout, directly above the Biltmore Hotel on the north shore of Lake Tahoe. A tree blocks much of the northern sky, and some of the light dome of Reno, but otherwise pretty good location. Seeing very good, transparency very good. Glare from nearby lights severe, especially to the west toward Tahoe City. Glare severely affects night vision, but by shielding eyes reasonbly dark skies near the zenith can be seen. Fairly good detail in the MIlky Way near zenith, washed out near the southern horizon. Incline Village has pretty good lights, not very obtrusive even though only a few kilometers away."
