   About 10 years ago, the Hamilton Centre of the RASC built a small, 
amature observatory.

  As luck would have it, a few months after completion, the local county 
errected a single streetlight maybe a 100 metres away.

  Untill thier compliants were heard,a nd the streetlight properly 
sheilded, the guys down there showed me a self - taught technique for 
taking out the streetlight.

  Thy wuld use a modified photo flash (such as te type used on a 35mm 
camera), fit the flash into the 2 inch focuser of their 17 inch 
newtonian, use the finder scope to centre directly on the electric eye - 
and fire th flash.

   They told me it took some practice, but after some time they became 
very good at knocking out the streetlight using the telescopeand 
flashgun.

  I have tried it myself, and it is amazingly effective if you aim is 
accurate.
