will be available to us this session.Astronomical Observing at Fishcreek - Friday 8/10/2007
This week we have a New Moon and lots of opportunity to observe those faint deep sky objects. Jupiter is currently our only 'show piece' planet to view since the Earth's path around the Sun has placed Venus and Saturn out of view - lost in the glare of the Sun until they both become observable in the morning before sunrise.

will be available to us this session.
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 1:30am 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.
Io will disappear behind Jupiter at 11:56 as the
video demonstrates.
'Alt' is degrees above the horizon, 'Az' is azimuth: 0 is north, 90 is
east, 180 is south and 270 is west
