Glendale
Stargazing Guide.
Just 17.1 miles from the center of Glendale, lies some of the region's best viewing at The Harken Observatory. We feature instrumented readings from Dune Trail to guarantee the most accurate sky quality data.
Stargazing Logistics for Glendale
- STEP 1. Primary Staging Area: The Harken Observatory. This is your most reliable community-vetted hub within a ~17.1 mile radius.
- STEP 2. Sky Quality Baseline: Classified as Class C (Suburban). Use the instrumented 5 rating from Dune Trail as your technical benchmark for the region.
- STEP 3. Local Support: Contact Milwaukee Astronomical Society for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Glendale offering varied horizons and atmospheric stability levels.
Glendale is positioned in a strategic 'Starlight Corridor.' It is far enough from the WI metro glare to allow for deep-sky imaging, yet serves as a convenient staging area for the deeper Class 5 skies found at Dune Trail.
The Best Times for Stargazing in Glendale
While Winter offers the most consistent clear nights for Glendale, wait for the 4-day window surrounding the New Moon each month for the deepest contrast. Since the sun sets early in the late Winter months, you can often begin deep-sky imaging as early as 7 PM.
Expert Tips for Glendale Observers
When observing from The Harken Observatory, try to position yourself facing away from the nearest major light dome. For Glendale residents, this usually means looking toward the rural horizons of WI to capture the lowest magnitude stars that are normally invisible from the city center. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Dune Trail (153.2 miles away) remains the benchmark for regional sky quality.
Best Spots for Stargazing in Glendale
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 Glendale spots to preserve your night vision.
The Harken Observatory
" Heading out from Glendale 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. "
Modine-Benstead Observatory
" A manageable drive from Glendale, this spot is a reliable regional favorite. Equipment Logic: Small aperture telescopes are actually more resilient to localized heat currents than large ones on suburban nights. "
Maywood Environmental Park
" Heading out from Glendale 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. "
Volo Bog
" Pack some snacks for the drive from Glendale; this destination is a justified detour. Light snacks and drinks will be available. Light snacks and drinks will be available. "
Harrington Beach State Park
" Heading out from Glendale 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. "

Access high-precision SQM readings from the National Park Service, providing the definitive baseline for regional darkness quality. Seeing the faint magnitude targets listed in these NPS readings often requires the specific gear we've staged for Glendale nights in our observer field kit.
Dune Trail
Sleeping Bear Dunes NL
Local Relevance
For observers in Glendale, Dune Trail serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Stars are soft, with a ring of moisture visible around bright stars. High airglow apparent. Milky Way just visible, no detials apparent. Travese City light dome dominates the eastern horizon. Reflection of Travese City dome is visible on Glen Lake, further impacting dark adaptation in that direction. Transparency improved over the night, with the best conditions at the end of data collection."
Kemil Beach
Indiana Dunes NL
Local Relevance
The scientific findings at Kemil Beach provide Glendale residents with the most reliable data on regional atmospheric stability.
"Set up about 50' from the water in a depression in the sand dunes. Local glare from the western most home in the "1933 Century of Progress" homes. Other glare sources from the power plants to the SW and NE along the lakeshore are easily visible but did not saturate the camera sensor. A clear view across Lake Michigan to the Chicago skyline, though clouds and haze never completely cleared away. I suspect the industrial developments from the Port of Indiana all the way around to Chicago has a significant impact on aeresols and local cloud development. Even so, at 35 miles distant, the illuminated buildings of the Chicago skyline were easily visible to the naked eye on this evening. The light dome of Michigan City (5 miles to the ENE) was very bright, but the dome from Chicago all the way to south of INDU is by far the greatest source of skyglow. The Milky Way was visible from 15° above the horizon at both ends. Not a lot of detail was visible in the Sagittarius or Cygnus star clouds. M31 was barely visible to the naked eye without using averted vision. Comparitively, for the region, this is not too bad a place to view the night sky. If not for the local glare sources, it would be fairly quick to dark adapt and be able to see many celestial features. Was able to see 6.2 LM in Ursa Major (which was over the lake to the darker north)."
