We hope to see you here for a night under the stars - now in our sixteenth year!
Tonight, we won't have the Moon to deal with until it clears the trees at 3:10am Saturday morning. However, we have beautiful Saturn with its magnificent rings, the colorful double stars and open clusters made up of hundreds of stars that will look beautiful; the globular clusters will be fantastic as will the planetary nebula formed by dying stars. The diffuse nebula and emission nebula where stars are being born will also be visible. Galaxies will be available to us as well.

How about the planets...which ones can we see tonight? 

    Sun is obviously unavailable to us, it IS night time after all. ;^)
    Mercury is setting an hour after sunset but is impossible to see since it's lost in the glare of the sun.
    Venus is now visible in the morning rising an hour before sunrise.
    Earth is what you'll be standing on as you look up. ;^)
    Mars is a morning object now, rising 2 hours before sunrise.
    Jupiter is an early morning object rising at 2:33am.
    Saturn is visible in the evening and night. It sets at 1:55am.
    Uranus rises at 1:21am.
    Neptune rises 1 minute after midnight.
 
  Pluto rises at sunset, but so incredibly small and dim that we can't see a thing in our telescopes!
    Moon is one day past third quarter and rises 40 minutes after midnight tonight.

     Question: Will Mars be "as big as a Full Moon on August 27!" ???
       Answer: ABSOLUTELY NOT!!!

     Question: Will there be "Two Full Moons in the Sky!" ???
       Answer: ABSOLUTELY NOT!!!

     Mars was the closest in recorded history on August 27, but that was only in 2003, not every year!
     At that time, it appeared to be 1/75th the apparent diameter of the Moon!  NOT the "same size as the Full Moon".
