Few weeks ago, camped in Eldorado National Forest, the Crystal Basin area.
20 mile from Taho.
At Gerle lake, it was so dark, I could see M51 with my Nikon 50 mm bino.
I can make out the shape of the double galaxy, no details though, only the
shape.
Very dark place, lake reflected all the stars on it's surface, like a
mirror. I wouldn't try to find my camp site without a light, for sure.
About 3 hours drive from Pleasanton on Hwy 50, located between Placerwille
and Taho, than drive beyond Union Valley reservoir.
