Astronomical Observing at Fishcreek - Friday 8/24/2007

This event will feature the nearly-full Moon, the planet Jupiter, colorful double stars, open clusters made up of hundreds of stars, globular clusters comprised of hundreds of thousands of stars, and a host of brighter deep sky objects.  The fainter objects will, unfortunately, be obscured by the brightness of the Moon.

We hope to see you here for a night under the stars - our twelfth year.

This animated GIF of Jupiter and its four moons begins at 8:00pm EDT and runs until Jupiter is
     below the horizon at 0:35am Saturday morning.  You can read the altitude and azimuth in the
     caption below Jupiter.  This image is neither inverted nor reversed - Jupiter will look like this in
     binoculars or a non-inverting telescope.  Frames are 15 minutes apart.
     'Alt' is degrees above the horizon, 'Az' is azimuth: 0 is north, 90 is east, 180 is south and 270 is west
