This is a mid-sized bright globular. At 150x it is finely resolved but the central region is not completely resolved. Even at 50x it is relatively well resolved. The level of concentration is rather weak. The bright central region looks pointed in three directions just like a maple leaf. The southeastern side of the center has not such extension but the outline is sharp with four stars shining outside it. A bright star off the northern side stands out. There is a conspicuous line of stars which encircles the edges of the globular and extends further to the south. This line of stars is clearly seen in photographs. This globular is full of interesting characteristics.
