The area was finally sufficiently smoke-free to host firefighters from @VCFD at the 60" telescope. We're pleased that we could thank them in some small way by treating them to views of Jupiter, Saturn, Mars, the Moon and others. We plan to do this with another group tonight. pic.twitter.com/dPB4r2N152
