Re: [Utah-astronomy] More on Commet Garradd - contending with neighborhood lights

The lamp comes on at night by a dark-sensing electric eye . . .

That helps. Just ask if your neighbor if you can hit the detector with a red laser when you are using your telescope. That will turn the light off. You can put a cheap $5 red light laser on a cheap camera tripod and aim the laser at the light detector. I also have a low-end carpentry laser straight-edge from Ace or Home Depot. That works best because it has a fixed on-off switch. Red laser presentation pointers often have a dead man button. Show your neighbor the Moon or Jupiter first. Clear Skies - Kurt
