Astronomical Observing at Fishcreek - Friday 07/17/2009

IMPORTANT UPDATE as of 7/17/09 at 6:00pm:

Once again, the weather has not cooperated with us.
This event has been Cancelled due to heavy cloud cover
and threat of thunderstorms.

We'll try again next week, Friday 7/24/09.

Tonight, we have a thin waning crescent Moon that won't clear the trees to the east of the observing field until after 3am.  This gives us a dark moon-free sky nearly the entire night.  We'll be able to see Saturn, colorful double stars, and open clusters made up of hundreds of stars.  The 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 will be available to us since we won't have to contend with the light of the Moon.  Saturn, the ringed planet, is a beautiful sight.  With a high-power view through the telescopes, the cloud bands are now visible since the rings are nearly edge-on this entire year.  Try to catch the rings now, or as soon as possible, because they'll continue to be more difficult to see as the year progresses becoming invisible to us by early September.

We hope to see you here for a night under the stars - now in our fourteenth year!
