Stargazing Logistics for Four Square Mile
- STEP 1. Primary Staging Area: Chamberlin Observatory. This is your most reliable community-vetted hub within a ~3.5 mile radius.
- STEP 2. Sky Quality Baseline: Classified as Class C (Suburban). Use the instrumented 6 rating from Coyote Ridge Parking as your technical benchmark for the region.
- STEP 3. Local Support: Contact Denver Astronomical Society for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Four Square Mile offering varied horizons and atmospheric stability levels.
Four Square Mile acts as a primary gateway to the Chamberlin Observatory zone. This proximity allows for scientific-grade viewing (Class 6) at Coyote Ridge Parking just a short 15-minute drive from the city center, making it a rare 'Hub' for serious observers.
The Best Times for Stargazing in Four Square Mile
For the best experience, target the late-night window between 1 AM and 4 AM in Four Square Mile. 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 Four Square Mile Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Four Square Mile, 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 CO region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 6 at Coyote Ridge Parking (56.5 miles away) remains the benchmark for regional sky quality.
