Messier 14 (also known as M14 or NGC 6402) is a globular cluster of stars in the constellation Ophiuchus.

Medium-sized telescopes will show some hint of the individual stars of which the brightest is of magnitude +14.

[6] A total of 70 variable stars are known in M14, many of the W Virginis variety common in globular clusters.

It is estimated that the nova reached a maximum brightness of magnitude +9.2, over five times brighter than the brightest 'normal' star in the cluster.

Slightly over 3° southwest of M14 lies the faint globular cluster NGC 6366.
