Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light—a little too much pseudoscience and not enough science.

According to Chernoff, this was an astrophotography-modified, mirrorless camera without any special filters. “It is about two and a half hours of total exposure time across 300 individual frames, stacked and processed together,” he said. “It was shot from a dark roadside location about an hour away from my home.”
