The Moon is one day before New, so we won’t have a chance to view it during this session..
We will just miss Venus and Mercury because they will set by8 pm. Jupiter and Saturn will be well placed in the sky and should provide terrific views. Jupiter’s Moons will provide good entertainment as Io will transit and Callisto passes just under the planet! Uranus and Neptune have joined the
group and will be visible in the East, with Uranus rising a little after 8 pm.
Late summer is an excellent time to view many Messier objects in the Sagittarius and Scorpius regions. Open clusters M8, M7 and M6 will be visible and globular clusters M22 and M4 will be visible. This might be the last time for the season to take a look at these spectacular objects!
We will take a look at the Wild Duck Cluster or M11 in Scutum . The globular cluster M13 in
Hercules will be visible, as is one of the brightest globular clusters called M15. The famous Double Cluster will also be available. We will be able to see our nearest neighbor galaxy, the Andromeda galaxy, if the skies are dark enough. Also overhead is the summer asterism of the Summer triangle which comprises the brighter stars Vega, Deneb and Altair (of Lyra, Cygnus and Aquila respectively).
September skies are full of interesting stars to look at through the telescope. We will test your eyesight with Alcor/Mizar in Ursa Major. We will also look at the most beautiful double star Albireo in Cygnus, the double-double star system in Lyra,
and Antares in Scorpius.
If time permits, we may also do some hunting for a few galaxies since we don’t have interference from Moonlight during this evening.
Come spend the evening viewing the cosmos with your family, residents and non-residents are welcome! Students, who are accompanied by their parents, are especially welcome! Please take note that the dome is not heated or cooled, so pay attention to the weather and dress in a manner that is appropriate for the evening temperature conditions. If it is raining or
cloudy, a planetarium program will be presented instead.
