One of my favorite objects in the sky is the Summer Triangle. For me it symbolizes the coming of cooler weather and clearer skies and it has been slowly rising in the early evening skies over the past several months. Now is the prime time to enjoy this beautiful asterism made up of Deneb, in Cygnus, Altair, in Aquila, and Vega, in Lyra.
There are plenty of objects within it boundary, including the constellation Sagitta.  Appropriately, Sagitta is Latin for “Arrow.” Even though this is the third smallest constellation (only Equuleus and Crux are smaller) it has been recognized since classical times.
One reason for it being so well recognized is because it can be seen from both hemispheres due to it proximity to the celestial equator.
Seemingly unusual for many constellations, this one looks just like what it is called, an arrow. During classical times it represented many arrows. It is the arrow that Hercules used to kill the eagle that Zeus sent to punish Prometheus, it is also the arrow shot by Heracles at the Stymphalian Birds, it is the one which Apollo used to slay the Cyclops, and it is said to represent Cupid’s arrow.
While, because of its size, there are not many deep sky objects within Sagitta’s boundary there is one beautiful globular cluster right in its center that can be seen with a pair of binoculars, M71. This globular cluster is about 13,000 light years distant, and is a little more than 7 minutes of arc in diameter (not quite as large or as bright as the famous Hercules cluster).
