Much of the US will be in the path of a solar eclipse on August 21, 2017. In honor of that event show us photos of any lunar or solar eclipse.
This is obviously a topic for later this year, perhaps early September.
Modifying this slightly to increase participation:
In honor of the Great American Eclipse of August 21, 2017, show us pictures from any solar or lunar eclipse. Crowd shots at an eclipse viewing gathering are fair game, as is the gum; stacked or HDR shots are not.
