Stargazing Logistics for Gunbarrel
- STEP 1. Primary Staging Area: Horsetooth Mtn Open Space. This is your most reliable community-vetted hub within a ~36.5 mile radius.
- STEP 2. Sky Quality Baseline: Classified as Class C (Suburban). Use the instrumented 5 rating from Bobcat Ridge as your technical benchmark for the region.
- STEP 3. Local Support: Contact Longmont Astronomical Society for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Gunbarrel offering varied horizons and atmospheric stability levels.
Gunbarrel is positioned in a strategic 'Starlight Corridor.' It is far enough from the CO metro glare to allow for deep-sky imaging, yet serves as a convenient staging area for the deeper Class 5 skies found at Bobcat Ridge.
The Best Times for Stargazing in Gunbarrel
For the best experience, target the late-night window between 1 AM and 4 AM in Gunbarrel. 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 Gunbarrel Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Gunbarrel, 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 5 at Bobcat Ridge (28.9 miles away) remains the benchmark for regional sky quality.

Bobcat Ridge
Fort Collins Natural Area
Local Relevance
For observers in Gunbarrel, Bobcat Ridge serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"One or two small clouds to the north, moving southeast. Transparency was good, seeing fair. Fort Collins light dome was bright and dominated the east horizon, while Loveland was easily visible to the southeast. Milky Way was visible as a complete arc,above the light domes, but fine detials were washed out."
Coyote Ridge
Fort Collins Natural Area
Local Relevance
Gunbarrel enthusiasts typically use the instrumented readings from Coyote Ridge to calibrate their deep-sky expectations for the area.
"Resolution Testing. 3 data sets collected in order to determine vertical and horizontal illuminance"
