TIL someone decided to point the Hubble Space Telescope at the Moon once: nasa.gov/images/content/136335

Now I want to know with large telescopes if there's a danger of setting fire to the sensor with moon-light?


@jhol Oddly enough I had a discussion about this on Twitter about a month ago. Maximum temperature achievable is no higher than Moon's surface (max ~120C). So a huge mirror could warm a person, but not set fire to anything.
