Tonight, we have a bright waning gibbous Moon that will be with us the entire night.  While this phase isn't the best for viewing detail in the craters on or near the terminator - the line separating lunar night from day, a wealth of features can still be seen.  We'll also be able to see Saturn (although quite low in the west) and Jupiter (when it clears the trees to the east of the observing field), 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 somewhat difficult in the light of the Moon.  Saturn, the ringed planet, is still 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.  Jupiter will clear the trees after 10:25pm and you'll see why it's called the King of the Planets.

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