Globular Cluster M71 (NGC 6838), class X-XI, in Sagitta.
RA 19:53.8 (h:m); DEC +18:47 (deg:m); Distance 13.000 light years
Visual Brightness 8.2 (mag); Apparent Dimension 7.2 (arc min)
This globular cluster is easy to find and nicely observable even in good binoculars, by locating the 6th-mag star 9 Sagittae half-way between Gamma and Delta of that constellation. Medium-sized amateur telescopes are required to resolve this compressed mass of stars, but then even the center is resolved. The cluster is brighter and sharply terminated on the western side, forming a "curving V", as John Mallas describes it.
