- Local Experts: Southern Colorado Astronomical Society
- Verified Observations: 2 distinct spots
If you’re looking to escape the light pollution of La Junta, you’re in luck. While enthusiasts often gather at Lake Pueblo Visitors Center for its accessibility, scientific audits conducted by the National Park Service at Atop Restroom provide the most accurate reading of the regional sky quality, measuring at a Bortle 4.0. The transition between the urban infrastructure of La Junta and the more rural stretches of CO creates several ‘dark sky’ corridors.
The Best Times for Stargazing in La Junta
For the best results in La Junta, aim for a ‘New Moon’ window. In these dark-sky conditions, the absence of moonlight allows the Milky Way to cast visible shadows.
Expert Tips for La Junta Observers
Because Lake Pueblo Visitors Center is a developed site, it often features established viewing pads and specialized equipment. For the best views at this spot, try to observe targets when they are highest in the sky to minimize atmospheric interference. Local enthusiasts often frequent this spot, making it a great place to meet experienced observers. Regardless of your gear, allow 30 minutes for your eyes to fully dark-adapt.

"Excellent data with smooth atmosphere, no layered haze or directional anomolies, stable extinction coefficient, and no clouds. 5th set shows some signs of dewfall. 4th set used for measurement as Milky Way was least prominent during that set. Data shows remarkable zenith brightness of 22.14 despite substantial light pollution to west. Measured LM of 6.7 at 45 deg to NW and 7.0 at 60 deg to NE. Glimpsed one mag 7.4 star. Visual scene is substantially hampered by streetlights along highway and park lighting, visible in images (especially at azi 305 deg). These impede dark adaptation and result in Bortle Class 4 rating, when potentially site could be Bortle Class 3. SQM of 21.73 at 06:15."

"Sky brightness is remarkably similar to 2007 data. This night was slightly more transparent, which will amplify distant light sources and dim close light sources. Denver brightness is much greater on this dataset, likely mostly due to snowcover on ground in Denver and to a lesser extend the lower extinction values on this night. As before, Colorado Springs could not be measured due to security lights at NPS maintenance bldg (303 degrees). Admin building lights are brightest light source at 286 degrees. Transparency was very good, seeing was below average. As before, dark adaptation was difficult. LM 6.8-7.0. SQM was 21.59 at beginning of data run and 21.64 at end. Combined BO080201A file into this one."
