Tonight, we have a nearly 90% illuminated waning gibbous Moon that will clear the trees to the east of the observing field just after midnight.  After that, its brightness will then be with us the rest of the night.  This phase isn't the best for viewing detail in the craters on or near the terminator - the line separating lunar night from day, but a wealth of features can still be seen.  We will 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 somewhat difficult in 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!
