| 説明 | 150 mm lens shot from the mountain station of the Palm Springs Aerial Tramway. Taken just before Florian starting shooting up the Tram with his backyard death laser.Here's Florian's description to Yahoo's Telescopes group:"Sent: Sunday, November 18, 2007 8:11Subject: Green laser pointer experimentI live in Palm Springs, Calif, just east of the San Jacinto mtns. The PS tramway upper station is about 7 miles line of sight from my backyard at at about the 8500' level. A few evenings ago i tried an experiment with Ray, a friend of mine. He was at the upper station and i was at home. At a pre-arranged time i shone (shined?) my 5mW green laser pointer at the upper tram station using my Tele Vue 76 to aim the beam. Ray said he had no trouble seeing my laser but that it wasn't particularly bright. It pretty much matched the brightness of streetlights and wasn't at all a blinding beam. Ray's photo is here with some additional comments... www.flickr.com/photos/fboyd/2042293386/After trying this experiment i feel a green laser pointer is certainly not a threat to an airplane flying miles away.°Florian Stargazing.com |
