Sagittarius, representing an archer (one of two constellations depicting half-horse, half-man centaurs), is prominent in the southern sky during the month of August in the evening. Although there are no first magnitude stars in it, there are plenty of second and third magnitude...but its main feature is that the Milky Way runs strong through it and there are many Messier objects...mainly nebula and star clusters...interspersed throughout. I picked it as my constellation of the month over a couple of others because of the striking presence of the planets Jupiter and Saturn in its northeastern corner right now. By the way, three of the names of Sagittarius's more prominent stars, Kaus Borealis, Kaus Media and Kaus Australis, are derived from two different languages...Arabic and Latin: "kaus" is "bow" and "borealis", "media" and "australis" translate to northern, middle and southern, respectively. Sagittarius is the last of the brighter zodiac constellations that march across the sky...at least for a few months: its followers...Capricornus, Aquarius, and Pisces...are pretty faint as the autumn evening sky has few bright stars of note. The above picture I drew just shows the brighter stars along with Jupiter, Saturn and the positions of some of the Messier objects...Sagittarius contains many more stars visible to the naked eye and encompasses a much wider area in the celestial sky than what I've shown...
