On this page I collect my observations of the globular star cluster M 14 (NGC 6402) in the constellation Ophiuchus.

Introduction

The globular star cluster M 14 is located in the constellation Ophiuchus/Serpent Bearer and the third brightest globular star cluster in this constellation.

M 14 (NGC 6402)
Size: 3' (Stoyan)
Distance: 33,000 light years (Stoyan)
Rating: * (Stoyan)

Find/Identify

Find: M 14 in Ophiuchus/Serpent Bearer is located to the left of the connecting line between Sabik and Cebalrai (about one third down from Cebalrai; see sky map above)

Identify: Since there is no other globular star cluster in the vicinity, the identification of M 14 should not be a problem.
