|SEE 7,000 STARS IN TONOPAH'S SKIES.
Experienced observers with good eyes can see stars as faint as visual
magnitude +7.0 at an extraordinarily dark site. About 14,000 stars are
brighter than magnitude +7.0. Since observers can see about half the
sky, they see about 7,000 stars. Observers in Tonopah can see stars of
magnitude +6.5 or +7.0.
Compare this to other areas. Because of light pollution, city
dwellers usually can see only 25 to 50 stars. The Milky Way is not
visible. Where light pollution shows only stars of magnitude +5.0
or brighter, about 800 stars are visible; the Milky Way is barely
visible, if at all.
Outside of large cities, light pollution is still a serious problem. The
Milky Way is never seen when fewer than 250 stars are visible. These are
magnitude +4.0 and brighter.

|How Dark Is It?
TONOPAH IS SURROUNDED BY SOME OF THE
DARKEST SKIES IN THE WORLD!
Observatories that were once in remote, dark areas now campaign to reduce
development. Light from growing communities makes observatory work
difficult. Obviously, most people live where there are many lights. If
they want to see stars, they have to come to a place like Tonopah.
People around the world are searching for dark skies. The International
Dark-Sky Association (IDA) organizes groups around the world to stop
light pollution of the sky. Find out more about this effort at their web
Observers travel to premier sky-viewing areas whenever viewing conditions
are good and especially when unusual sky events occur. Sky parties
are one way people can enjoy dark skies. Many families like to just get
out of the city and take the family to see the Milky Way. It is very
bright from Tonopah on clear moonless nights. How many stars can
you see with the
unaided eye? This depends on the experience of the observer, how dilated
the eyes are, the amount of sky light from electric lights and the moon,
and the clarity of the sky.
