Orion and Barnard's Loop over ancient basalt pillars

The magenta glow is from emission nebulae which occurs when dense interstellar gas clouds react with extremely hot stars and emit light in photons at a discreet wavelength. After days of constant cloud cover throughout Washington, it was refreshing to be out again doing what I love. Nothing puts thing into perspective more than gazing up at the starry night sky. The sky is tracked at 3 minutes, F/2.8, ISO 800 blended with a foreground exposure shot right after with tracker turned off at the same settings
