erate doofus to spoil a star party. Don't
be that doofus. If you're in a group of
people, don't go flashing your laser all
around the sky. If someone is photographing
nearby, make sure you don't
laser-bomb their photo. Don't use an
insanely bright laser. (Five milliwatts is
plenty - and that's the legal limit in the
U.S. anyway.) Don't shine it even close
to anyone's head, or at any airplanes.
It should only take you a few brief
flashes to zero in on your target. Used
properly, a laser finder can be unobtrusive
and extremely useful. And it can
save you a lot of back pain.

remembers when lasers were invented,
and some wag called them " a solution
in search of a problem. " Contact Jerry at

S&T's Pocket Sky Atlas
in Two Handy Sizes!
Starting with our famous Pocket
Sky Atlas, we wanted a clear and
detailed atlas that was easy to
use, compact, and convenient to
consult at the telescope.
Sky & Telescope's Pocket Sky Atlas
by Roger W. Sinnott
Then we magnified its 80 charts by
30% and added six additional closeup
fields, including " Steam from the
Teapot " and " The Scorpion's Tail. "
