[Laser] Sky illumination experiment

[Laser at KatHouse1.com]

I am being real.  That's our local ordinance.  No lights pointing skyward.
Those 360 degree globes are also illegal.

The local high school was required to install modern anti-pollution
lighting.  It has very little affect on the night sky during the summer.  So
it can be done.  However, when there is snow on the ground then it's an
entirely different matter.

A single light pointed skyward (or the wrong way) can be extremely annoying
depending on who your neighbors are.  If there happens to be an outdoor
lighting ordinance against this sort of thing where you are attemtping it
you could be in for quite a shock as I found out.  The expensive way.
