Conditions were wonderful all day and it looked as though we'd have a great night.  We were disappointed to watch clouds moving in from the north west at 10:00pm and we finally gave up at midnight and packed up the telescopes.
We did get great views of Saturn prior to the clouds.

 

Tonight's event will, again, be somewhat limited by a nearly full Moon the entire night.  We will be able to see the beautiful planet Saturn, 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.

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