Tonight, we're essentially Moon-free for nearly the entire night.  We have a 9% illuminated (waning crescent) Moon that won't rise until 4:55am Saturday morning.  This is one of those nights we wait for since all the faint DSOs (Deep Space Objects) will be visible due to the absence of the Moon.  Jupiter will be beautiful with the GRS visible at a convenient time, and Ganymede's shadow transit, too.  Take a look at the information for Jupiter, below.  We have the colorful double stars, 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.  Galaxies, including M31 - the Andromeda Galaxy - our closest neighboring island universe - will be ours for the asking.  Bring binoculars if you have a pair and we'll show you how to find the Andromeda Galaxy with them!  Also, we'll show you how to find the beautiful "Coat hanger" cluster which is best seen in binoculars.  Perhaps Kemble's Cascade will be high enough in altitude for us to see as well.

We hope to see you here for a night under the stars - now in our fifteenth year!

On 11/13/2009 at 6:10:53pm the Moon will be 34.9 below the west horizon
but will look similar to this at very low power* in our telescopes after it rises before sunrise tomorrow morning...

*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.
