Tonight we're Moon-less for the entire session since it set at 2:28pm this afternoon.  We'll have our pick of the available DSO's (Deep Space Objects) we love to see, including the M-objects and NGC objects.  Mars can be seen tonight since it'll set at 7:17pm - 2hrs 3min after sunset.  Jupiter is now magnificent as the night's show-piece.  It rises at 6:31pm and will be with us all night.  Uranus rises at 3:17pm and Neptune rises at 1:55pm. Both will be visible for us.  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.  Many galaxies will be available to us.  Bring your binoculars and we'll show you how to find the Andromeda Galaxy with them!

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

    Sun is obviously unavailable to us, it will be night time after all 
    Mercury sets 39min after sunset and we'll try to see it despite the glare of the Sun
    Venus rises 2hrs 50min before sunrise and is an incredibly bright 83% illuminated waxing gibbous
    Earth is what you'll be standing on as you look up 
    Mars is low on the horizon but still visible tonight and sets at 7:17pm - 2hrs 3min after sunset
    Jupiter rises at 6:31pm and will clear the trees by 8:05pm
    Saturn is gone from sight setting at 4:46pm - 28 minutes before sunset
    Uranus rises at 3:17pm and will be visible this evening
    Neptune rises at 1:55pm and is visible this evening
 
  Pluto sets at 8:33pm, 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 is a 21% illuminated waning crescent setting 2hrs 46min before sunset

Below is the current image of the Sun in densely-filtered white light updated each morning on the SOHO site.
Notice the graphic below the image that shows the relative size of Jupiter and Earth compared to the Sun:
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 11/9/2012 at 6:13:55pm the Moon will be 39.8 below the west-northwest horizon
but would look like this at low power
* in our telescopes at 4:40am tomorrow morning when it reaches 15 above the horizon:

*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: This graphic is a correct-image representation.  A telescope will reverse this left-right and possibly invert up-down depending on type of equipment being used.

On 11/9/2012 at 6:13:55pm Mars will be 8.4 above the southwest 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".
