Notes:
Messier 22 (M22) is a globular cluster located near the Milky Way bulge, the tightly packed group of stars near the galactic centre. With a visual magnitude of 5.5, M22 is the brightest globular cluster visible from the mid-northern latitudes. However, as it lies in the southern constellation Sagittarius, M22 never rises very high in the sky.
