Frequently asked
Is tonight good for stargazing at Bighorn Mountains?
The live score above pulls today's forecast and runs it through StarCast's scoring model, factoring in cloud cover, moon illumination, Bortle class, humidity, and atmospheric transparency. Above 70 is an excellent night. Below 40, conditions are poor. The score updates daily.
What makes Bighorn Mountains good for astrophotography?
The Bighorn Mountains rise abruptly from the Wyoming plains to peaks above 13,000 feet in Bighorn National Forest. The isolation of the range from major population centers means the skies are consistently dark: Sheridan to the north and Worland to the west are both small cities, and the surrounding high desert basin is sparsely developed. Alpine lakes, spruce forests, and dramatic granite ridgelines give photographers a wide range of foreground environments. US Highway 14 crosses the range at Cloud Peak Overlook near 9,000 feet, which is one of the most accessible high-elevation shooting positions in Wyoming.
When is the Milky Way visible at Bighorn Mountains?
The galactic core is visible from April through October. High-elevation roads in the Bighorn range typically open in late May or early June depending on snowpack. June through August is the primary window for combining accessible high-altitude shooting positions with good core altitude. Alpine weather can change quickly: afternoon thunderstorms are common in summer, but evenings often clear. Bring layers even in July, as temperatures drop sharply after dark at elevation.
