Tonight we'll have an 85% illuminated waxing gibbous Moon with us until it sets at 4:16am tomorrow morning.  The DSO's (Deep Space Objects) we love to see will be difficult the entire night.  Jupiter will be visible by 9:30pm after it clears the trees to the east of the observing field.  There won't be any Jovian moon activity, but the GRS transits the planet at 9:40pm and should be easy to see.  Uranus and Neptune are up, but rather unimpressive being so far away.  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 be visible.  Galaxies will be available to us,  Bring your binoculars and we'll show you how to find the Andromeda Galaxy!

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

    Sun is obviously unavailable to us, it will be night time after all. 
    Mercury is setting 16 minutes after sunset and is completely lost in the glare of the Sun.
    Venus is now setting 36 minutes after sunset and lost in the glare of the Sun.
    Earth is what you'll be standing on as you look up. 
    Mars is a late night object now, rising at 2:02am and is now 4° east of the M44 - the Beehive Cluster
    Jupiter is a night object rising at 7:53pm.
    Saturn is no longer visible since it sets 21 minutes after the Sun.
    Uranus rises at 6:23pm.
    Neptune rises at 5:02pm.
 
  Pluto rises at 1:46pm, but so incredibly small and dim that we can't see a thing in our telescopes!  We can show you where it is.  OK, OK...if you want to try to see it, we'll try.  Don't expect to see anything, though!
    Moon will be an 85% illuminated waxing gibbous rising at 4:38pm.  It will be our constant companion tonight.
    Comet Garradd (C/2009 P1) is now easily visible at magnitude 8.0 in the constellation Hercules

Never EVER point your telescope at the Sun!!!  Instantaneous and permanent eye damage will result!!!
Very special equipment is required to provide an image like this...don't try this at home.

On 10/7/2011 at 7:57:33pm the Moon will be 30.9° above the southeast horizon
and will look like this in our telescopes at low power*:

*
How do we change the "power" (magnification) of our telescopes?
Simple!  By changing the eyepiece to one of a longer or shorter focal length.
If the eyepiece is of shorter focal length, the "power" (magnification) is higher,
If he eyepiece is of longer focal length, the "power" (magnification) is lower.
By how much?  Here's the formula:
Magnification =F focal length of telescope objective lens (or mirror)
focal length of eyepiece being used      

Note: All graphics are correct-image representations.  A telescope will reverse this left-right and possibly invert up-down depending on type of equipment being used.

On 10/7/2011 at 7:57:33pm Mars will be 27.5° below the north-northwest horizon

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 1/75
th the apparent diameter of the Moon!  NOT the "same size as the Full Moon".
