从地球加州海岸的雷耶斯角眺望太平洋的夜空中，北方的冬季星座和银河系的长弧正在形成。天狼星，大犬座的阿尔法星，在星空弧线的左边很显眼。猎户座的淡黄色参宿四、金牛座的毕宿五和蓝色的昴宿星团也位于银河系和西北地平线之间，靠近画面中心。这张全景图是在三月初拍摄的，但它太暗了，无法用肉眼看到。在那个北方的夜晚，它们膨胀的光芒包括猎户座的巴纳德环和昴星团（也被称为加利福尼亚星云）上方和右侧的NGC 1499的红色半圆。

Northern winter constellations and a long arc of the Milky Way are setting in this night skyscape looking toward the Pacific Ocean from Point Reyes on planet Earth's California coast. Sirius, alpha star of Canis Major, is prominent below the starry arc toward the left. Orion's yellowish Betelgeuse, Aldebaran in Taurus, and the blue tinted Pleiades star cluster also find themselves between Milky Way and northwestern horizon near the center of the scene. The nebulae visible in the series of exposures used to construct this panoramic view were captured in early March, but are just too faint to be seen with the unaided eye. On that northern night their expansive glow includes the reddish semi-circle of Barnard's Loop in Orion and NGC 1499 above and right of the Pleiades, also known as the California Nebula.
