Coolidge
Stargazing Guide.
Just 21.3 miles from the center of Coolidge, lies some of the region's best viewing at Picacho Peak State Park. We feature instrumented readings from Compound B to guarantee the most accurate sky quality data.
Stargazing Logistics for Coolidge
- STEP 1. Primary Staging Area: Picacho Peak State Park. This is your most reliable community-vetted hub within a ~21.3 mile radius.
- STEP 2. Sky Quality Baseline: Classified as Class D (Urban). Use the instrumented 7 rating from Compound B as your technical benchmark for the region.
- STEP 3. Local Support: Contact East Valley Astronomy Club (EVAC) for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Coolidge offering varied horizons and atmospheric stability levels.
Coolidge is positioned in a strategic 'Starlight Corridor.' It is far enough from the AZ metro glare to allow for deep-sky imaging, yet serves as a convenient staging area for the deeper Class 7 skies found at Compound B.
The Best Times for Stargazing in Coolidge
For the best experience, target the late-night window between 1 AM and 4 AM in Coolidge. This is when local industrial lighting and residential 'sky glow' is at its minimum, and the most prominent Winter constellations are directly overhead at the zenith.
Expert Tips for Coolidge Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Coolidge, looking slightly to the side of a faint nebula will reveal much more detail than looking directly at it, especially when dealing with the Class 5+ suburban skies of the AZ region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 7 at Compound B (4.4 miles away) remains the benchmark for regional sky quality.

Compound B
Casa Grande NM
Local Relevance
Coolidge enthusiasts typically use the instrumented readings from Compound B to calibrate their deep-sky expectations for the area.
"M31 a difficult direct/ easy averted vision object. M33 not visible. Milky way not visible (perhaps very fainly around Cassieopea, Perseus). Multiple light domes apparent, as well as many small glows from nearby development. Towers with red flashing lights and lots of air traffic present. A very clear night, but windy. Its possible some dust might be in the air."
North of Compound B

Local Relevance
Coolidge enthusiasts typically use the instrumented readings from North of Compound B to calibrate their deep-sky expectations for the area.
"High thin clouds presnt, especially to the north. M31 a difficult direct vision, or an easy averted vision object. Multiple light domes are apparent as well as some closer lights from development around Coolidge."
