Last weekend's star gazing at Palomar Observatory Campground had probably the darkest sky I've ever seen at this location. The reason? We were expecting a storm to move in on Sunday, and during Saturday night, the clouds covered the nearby cities for a few hours before covering the mountain top.
At 1:00 pm, looking south at the Milky Way, you could detect dustlanes that look like a horse standing above the back of Scorpius. I've never seen this before. Double-click the photos below to enlarge the image, if necessary. The horse is diagrammed in the third image along with Scorpius.
