When observing from verified local spots, try to position yourself facing away from the nearest major light dome. For Sidney residents, this usually means looking toward the rural horizons of MT to capture the lowest magnitude stars that are normally invisible from the city center. Scientific Context: While local conditions vary, the instrumented reading of Bortle 3 at Oxbow Overlook (34.7 miles away) remains the benchmark for regional sky quality.

Rendezvous Grounds
Fort Union Trading Post NHS
Local Relevance
The scientific findings at Rendezvous Grounds provide Sidney residents with the most reliable data on regional atmospheric stability.
"Set up camera due north of the fort on the Rendezvous Grounds. An excellent evening with warm temperatures and almost no wind. The motin sensor light mounted amongst the HVAC equipment repeatedly turned on every few minutes even with no movement on my part and no obvious wildlife. The light, when on, is extremely bright and lights up the entire NW outer wall and a large area of the adjacent grounds. I tried covering it for the first set, but it was still too bright, but I got lucky in the second data set in that it was off when the camera was pointing in that direction. The only other outdoor light in the vicinity was in the upper parking lot, though it was fully shielded. It is too bright for the intended task (too many lumens). The light dome from Dickinson was easily visible to the ENE and Watford City somewhat visible to the SSE. A handful of yard lights can be seen around the horizon from private ranches, though they do not impact the night sky measures. The night sky quality was very good and details could be seen in the Milky Way. Perhaps the downturn in oil prices has reduced the activity in the surrounding area."
