Arcturus

Arcturus’ bright light was used to open the 1933 World’s Fair in the host city Chicago, Illinois (USA). Back then, people thought Arcturus was 40 light years away from Earth, so it was chosen to go along with the 40th anniversary of the previous Chicago World’s Fair in 1893.

August's full moon goes by a lot of names, including the Sturgeon Moon, the Green Corn Moon, the Raksha Bandhan Moon, Nikini Soya, and the end of the Esala Perahera festival.

It is called the Sturgeon moon because during this time of the year, there is supposed to be lots of sturgeons out swimming around. Here is a link to some more information:

I was able to get to see some of this year's Draconid meteor shower (*1.), it was a bit different. Usually the meteors I get to see have longer lasting bright flashes as they come whizzing down out of the sky, these tended to be less colorful, but still very neat to see.

Auriga The Charioteer. This constellation usually shows up in the Northern Hemisphere during the late fall, early winter months. Its shape is easy to recognize and with its mainstay star Capella being so bright, it is easy to find.

(constellation stars are listed in red, DSOs are listed in green.)

Auriga is itself home to lots and lots of DSOs (deep sky objects --- various kinds of nebulas, galaxies, star clusters, etc.) one of these is IC 405, the Flaming Star Nebula:

This is the equivalent of a 30 minute exposure.
