This event was CANCELLED
due to clouds, rain, high winds and
completely soaked observing field
(This, most definitely, has *not* been a good year for astronomy!!)

We'll try again, but no event is currently planned.

Tonight we're Moon-free until it rises at 1:25am tomorrow morning.  The DSOs (Deep Space Objects) we love to see will be easy for us the entire night.  Jupiter will be visible by 8:20pm after it clears the trees to the east of the observing field.  We'll have an opportunity to see Jupiter's closest moon, Io, appear from behind Jupiter at 9:04pm tonight and a GRS (Great Red Spot) transit the planet at 11:10pm.  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 32 minutes after sunset and will soon be visible in the west after sunset.
    Venus is now setting 46 minutes after sunset and will soon be visible in the west after sunset.
    Earth is what you'll be standing on as you look up. 
    Mars is a late night object now, rising at 1:48am and is now half way between Regulus and M44
    Jupiter is an easy object all night now.  It rises at 6:53pm.
    Saturn is no longer visible since it sets 8 minutes before the Sun.
    Uranus rises at 5:27pm.
    Neptune rises at 4:07pm.
 
  Pluto rises at 12:52pm, 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 a 30% waning crescent rising at 1:25am.  It won't interfere with seeing the dim objects tonight.
    Comet Garradd (C/2009 P1) is now easily visible at magnitude 7.9 in the constellation Hercules

but would look like this in our telescopes at low power* at 4:00am tomorrow morning when it clears the trees to the east of the observing field:
 
*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 10/21/2011 at 7:36:23pm Mars will be 29.7° 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 1/75th the apparent diameter of the Moon!  NOT the "same size as the Full Moon".

Venus is setting 46 minutes after sunset.  Venus & Mercury appear to be 3° from each other, but only 15° from the Sun and lost in its glare.
Mars will reach western quadrature on Dec 2, 2011.  It's now getting closer and will be closest on 3/3/2012

Outer Solar System - the Sun, Jupiter, Uranus, Neptune and Pluto on 10/21/2011
(Created using Software Bisque's TheSky software)
The Earth is catching up with Jupiter which will reach opposition one week from tonight.  At that time, it will be closest to Earth.
Saturn reached conjunction on Oct 13, 2011 and is now setting at 6:31pm.  It's totally lost in the glare of the Sun.
Uranus reached opposition on Sep 25, 2011 and rises at 5:27pm
Neptune reached opposition on Aug 22, 2011 and rises at 4:07pm
Pluto's orbit can be seen to be extremely eccentric (non-circular) and tilted to the plane of the ecliptic.  It reached opposition on June 28, 2011
