Event has been cancelled due to cloud cover.

 

Tonight's event will feature a Moonless sky all night since it sets at 7:13pm this evening.  We'll have the planet Jupiter, colorful double stars, open clusters made up of hundreds of stars, 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, will all be available to us the entire night.  Many amateur astronomers feel that late fall is the best time to observe since there are beautiful objects of all categories available and the Milky Way, the galaxy in which we live, is directly overhead.

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

This animated GIF of Jupiter and its four moons begins at 7:00pm EDT and runs until Jupiter is below
the horizon.  You can read the altitude and azimuth in the caption below Jupiter.  This image is neither inverted
nor reversed and will look like this in binoculars or a non-inverting telescope.  Frames are 15 minutes apart.
'Alt' is degrees above the horizon, 'Az' is degrees of azimuth: 0 is north, 90 is east, 180 is south and 270 is west
Callisto is off-screen to the right

The apparent eastward (left) motion of Jupiter and its moons relative to the background
stars is due to the combined motion of Jupiter and Earth in their orbits around the Sun.
