Event report...
The sky wasn't looking too
promising, we had the equipment ready to set up, but gave up when clouds totally
obscured
the sky. We'll try again next Friday.
If amateur astronomy teaches anything, it's patience!

Tonight's
event will, again, be somewhat limited by a nearly full Moon the entire night.
We will be able to see the beautiful planets
Saturn
and
Jupiter,
colorful double
stars,
open clusters made up of hundreds of stars,
globular clusters comprised
of hundreds of thousands of stars. Unfortunately, the
planetary nebula formed by dying stars,
diffuse nebula and
emission nebula where stars are being born, and
galaxies will be
rendered invisible to us by the brightness of the full Moon. Saturn is beautiful beyond words!
If you've never seen Saturn through a telescope, you owe it to yourself to do
so. It's said that one picture is worth a thousand words, but no picture
can match the majesty of the real thing! Jupiter is visible, if you stay
after midnight when it will be high enough to clear the trees to our east.
This is an ideal time to view Jupiter. It reached opposition on July 9th
and is still about as close to us as it ever gets. With a high-power view
through the telescopes, details in the cloud bands is possible, and the four
Galilean moons actually appear as disks instead of just point light sources. Jupiter clears the trees to the
east of our observing field at a conveniently early hour now (see the
Outer Solar System
to see why this is so).
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!
