Delaware
Stargazing Guide.
Discover why the Delaware area serves as a strategic corridor for OH observers. We combine community-vetted spots like Warren Rupp Observatory with professional NPS sky reports at Blackrock Summit for a complete astronomical perspective.
Stargazing Logistics for Delaware
- STEP 1. Primary Staging Area: Warren Rupp Observatory. This is your most reliable community-vetted hub within a ~37.6 mile radius.
- STEP 2. Sky Quality Baseline: Classified as Class C (Suburban). Use the instrumented 5 rating from Blackrock Summit as your technical benchmark for the region.
- STEP 3. Local Support: Contact Columbus Astronomical Society for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Delaware offering varied horizons and atmospheric stability levels.
Delaware is positioned in a strategic 'Starlight Corridor.' It is far enough from the OH metro glare to allow for deep-sky imaging, yet serves as a convenient staging area for the deeper Class 5 skies found at Blackrock Summit.
The Best Times for Stargazing in Delaware
In OH, the transitional periods of early Summer often provide a stable atmosphere between weather fronts. For Delaware residents, this means less 'star twinkling' (scintillation) and a significantly steadier view for high-magnification planetary observation.
Expert Tips for Delaware Observers
If you're visiting Warren Rupp 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 OH during the peak viewing seasons. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Blackrock Summit (272.2 miles away) remains the benchmark for regional sky quality.

Warren Rupp Observatory
" Delaware observers often find this mid-distance site perfect for a full session. Thermal Mastery: Set your telescope out an hour early to allow the mirrors to reach 'thermal equilibrium' with the night air. "

Lowe-Volk Nature Center
" Heading out from Delaware toward this location will reward you with steady horizons. Meteor Watching Tip: Don't look at one spot; keep your eyes moving across the sky. Your peripheral vision is more sensitive to motion. "
The Lewis Observatory, Ohio University Zanesville
" For the dedicated Delaware observer, this spot offers a superior escape from light pollution. Observation Hack: Use a planisphere or a printed star chart under a red light instead of a digital app for the most authentic experience. "
Schoonover Observatory
" While it's a bit of a journey from Delaware, the sky quality here is worth the fuel. Parking is available in the grass along the main drive leading up to the observatory. Be advised that climbing a flight of stairs will be necessary to access the observatory dome. "

Blackrock Summit
Shenendoah NP
Local Relevance
For observers in Delaware, Blackrock Summit serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Exceptionally clear skies and air for this eastern US site. Very dry air with some moderate winds provided visibility of 50-75+ miles during the day. At night the horizon is almost completely illuminated by cities, small towns and rural farms and ranches. Some very bright direct glare sources in the cities of Harrisonburg and Fishersville (Hospital?). The Milky Way was visible to the horizon in the SW and obscured at about 25 degrees above horizon in the NE."
Kemil Beach
Indiana Dunes NL
Local Relevance
For observers in Delaware, Kemil Beach serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"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."
