At sites near Lewistown, 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 MT region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 3 at Calhoun Hill (141.3 miles away) remains the benchmark for regional sky quality.

Calhoun Hill
Little Bighorn Battlefield NM
Local Relevance
Lewistown enthusiasts typically use the instrumented readings from Calhoun Hill to calibrate their deep-sky expectations for the area.
"Billings and Sheridan light domes visible but not bright. Overall the direct glare was distracting, but blocking this allowed for dark adaptation. Milky Way was easily seen with detail in sagittarius, and dust lanes. Visible from tail of Scorpius in South to Cassiopeia. SQM 21.64 at 0130; SQM-L 21.63 at 0152."
Devil Canyon Overlook
Bighorn Canyon NRA
Local Relevance
The scientific findings at Devil Canyon Overlook provide Lewistown residents with the most reliable data on regional atmospheric stability.
"Clear skies, aside from some low clouds on the northern horizon, which mostly cleared out by 9:00 pm local time. Excellent site along the canyon rim with a direct view down into the town of Lovell. Another night of high airglow similar to the previous night at DETO. Milky Way overhead, but fine detail somewhat washed out toward the horizon and in the Sagitarrius star cloud by the airglow. Prancing Horse barely visible. Daytime visibilty slightly impaired by agricultural burning in the Big Horn Valley. The Devil Canyon Overlook is a great spot for observing the night sky or astrophotography. The Horseshoe Bend Campground is even more protected by terrain from the direct glare of Lovell."
