Event report:
Good conditions early but the 'seeing' deteriorated around midnight.
Overall, a successful event!
Attendees got to see Mercury prior to setting
at 10:30pm. Saturn was just incredible!
As predicted, the nearly full Moon and slight haze
limited deepsky viewing
to a few of the brightest open & globular star clusters. |
|
Tonight's
event will be somewhat limited by a nearly full Moon setting at 4:27am Saturday
morning.
Planet-wise, we'll have a last chance to catch fleeting Mercury in the west before it
gets lost in the glare of the Sun. We'll also see beautiful planet
Saturn,
colorful double
stars,
open clusters made up of hundreds of stars,
globular clusters comprised
of hundreds of thousands of stars. Unfortunately, the
planetary nebula formed by dying stars,
diffuse nebula and
emission nebula where stars are being born, and
galaxies will be
rendered invisible to us by the brightness of the full Moon. Saturn is beautiful beyond words!
If you've never seen Saturn through a telescope, you owe it to yourself to do
so. It's said that one picture is worth a thousand words, but no picture
can match the majesty of the real thing!
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!
