Local Observation Strategy

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.

Regional Perspective: Glendale is situated just 4.9 miles from Milwaukee, but its local horizon often provides a more stable viewing experience for planetary targets.

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."

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)."

The Celestial Photographer's Staging Advice

Gearing Up for Glendale Nights

"Staging for a night near Glendale requires a balance of power and portability. Consider 10x50 binoculars as a primary scouting tool while your main telescope acclimates to the cooler rural air."

The Glendale Field Kit

Designing a field kit for Glendale requires understanding the specific transition from urban skyglow to the regional suburban benchmarks. Since The Harken Observatory offers a specific Class 5 horizon, your equipment needs to be calibrated for the unique transparency found in this part of the state.
