Event report...
This event has been cancelled
due to heavy cloud cover
and threat of rain. We'll try again next
Friday 9/12/08.
If amateur astronomy teaches anything, it's patience!

The Moon is in the best phase for viewing detail
on the terminator - the line separating lunar day from night. It sets
early enough (10:28pm) to allow us to view deep sky objects without having to
stay up too late. We'll be able to see
Jupiter,
colorful double
stars,
open clusters made up of hundreds of stars,
globular clusters comprised
of hundreds of thousands of stars,
planetary nebula formed by dying stars,
diffuse nebula and
emission nebula where stars are being born, and
galaxies. With a high-power view through the telescopes, detail in
the cloud bands of Jupiter will be possible, and the four Galilean moons actually appear as
disks instead of just point light sources. Uranus and Neptune are visible
now as well and appear as small bluish-green 'large' stars in our telescopes.
for a list of DeepSky Objects that
will be available to us this session.
We hope to see you here for a night under the stars -
now in our fourteenth year!
