Loomis
Stargazing Guide.
Just 18.5 miles from the center of Loomis, 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 Loomis
- STEP 1. Primary Staging Area: Community Observatory. This is your most reliable community-vetted hub within a ~18.5 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 Community Observatory for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Loomis offering varied horizons and atmospheric stability levels.
Loomis 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 Loomis
Observation in Loomis 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 Loomis Observers
Thermal equilibrium is key. Since Loomis temperatures can shift rapidly after sunset, allow your telescope mirrors at least 45 minutes to 'cool down' before attempting high-magnification work at Community Observatory. This prevents 'tube currents' from blurring your view of Jupiter or Saturn. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Buckhorn Group Camp (93.8 miles away) remains the benchmark for regional sky quality.
Best Spots for Stargazing in Loomis
The most accessible and reliable viewing locations in the region, ranked by local observer feedback. Pro Tip: Always bring a red-light flashlight to these Loomis spots to preserve your night vision.
Community Observatory
" Heading out from Loomis toward this location will reward you with steady horizons. Deep Sky Advice: Allow at least 20 minutes in total darkness for your pupils to fully dilate. You'll notice faint nebulae that were invisible at first. "
Folsom Powerhouse State Historic Park
" Just a quick dash for Loomis residents, this location offers great convenience. Vision Technique: Try 'Averted Vision'—look slightly to the side of a faint object to use the more light-sensitive rods in your eyes. "
Mount Diablo - Lower Summit Parking Lot
" While it's a bit of a journey from Loomis, the sky quality here is worth the fuel. 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 Loomis toward this location will reward you with steady horizons. Sky Contrast Tip: To see the Milky Way, wait for the Moon to go below the horizon; even a 25% crescent Moon can wash out the faintest nebulae. "
Aerospace Museum of California
" A short hop from Loomis, this spot is a top-tier local choice. Comfort Tip: The ground cools faster than the air. Bring a reclining chair to keep your neck strain-free during marathon observation sessions. "

Sky Quality Reports for Loomis
Access high-precision SQM readings from the National Park Service, providing the definitive baseline for regional darkness quality. To resolve the deep-sky objects measured in these scientific reports, Loomis observers should check our recommended optics kit.
Buckhorn Group Camp
Black Butte Lake RA
Local Relevance
Loomis 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
For observers in Loomis, State Line Lookout serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"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."
