Just academically, you understand, this could be
accomplished with a mechanical device that actuates a can of spray paint at the end of a long pole. :-) -An anonymous guy using Larry Curcio's account Philip wrote: Can anyone please give me some information, on turnung street lights off.

They may have timer/calendar chips on them so they are not sensitive to light coming in. In that case, you are out of luck. Lights have a photocell and a relay to turn them on at dusk and off at dawn. There's a capacitor in the circuit to add a little delay so a brief flash of light won't turn them off. The ones that turn off from the headlights of a passing car probably are defective. If you can shine long enough a light bright enough the streetlight goes out. I think this really is a bad idea. Instead go to a dark location or watch the moon and planets, which are bright enough for streetlights not to be a bother. |

What kind of locations do you look for when seeking a dark sky site? I tried once throwing my scope in the car and driving out to the country. I found farmers fenced off properties everywhere and not a single open publicly accessable area to be found ![]() I have also considered the BB gun option, but my neighbours know I have a telescope and they would know who to look for ![]() |

The real problem is that the lights follow you. Everything is fine and then suddenly there is a subdivision all around you. Your friendly local astronomy club probably has sites already arranged for. Go join up. Now. Uncle Al wants you! |
