Event report...
Amazing - two Fridays of good
weather in a row!
We had a fantastic night of observing. Jupiter's moon,
Io, kept us enthralled with its motion across the surface
of Jupiter followed by its shadow.
If amateur astronomy teaches anything, it's patience...
and tonight, our patience rewarded us handsomely - again!
|
|
|
Tonight's event will, again, be somewhat limited by the full Moon the
entire night. Despite the brightness of the moon, we will be able to see
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, and
galaxies. Jupiter, the King of the planets, is
a beautiful sight. With a high-power view
through the telescopes, details in the cloud bands is possible, and the four
Galilean moons actually appear as disks instead of just point light sources.
for a list of DeepSky Objects that
will be available to us this session.
We hope to see you here for a night under the stars -
now in our fourteenth year!
