Cali In The Sky
Drifting through the Orion Arm of the Milky Way is the California Nebula, a cloud of glowing hydrogen and sulfur gases with a wispy veil of oxygen. More than 100 light-years long, this "California shaped" mass is not far from the Pleiades star cluster in the constellation Perseus. In this rendition I see the Sierra Nevada mountains represented by the nebular ridges along the northeastern edge of the object, while the Pacific Ocean is represented by the veil of glowing oxygen fanning out from southwestern edge. I was fortunate to have clear, good quality skies for three successive nights, allowing me to collect more than 25 hours of excellent exposures.
22.3 hours total exposure of hydrogen, oxygen, and sulfur emissions.
