M 14 - Globullar Cluster in the constellation Ophiuchus

Messier 14 is with more than 1 million solar masses the most massive, but due to the extinction of the dark clouds in front of it the faintest of the 5 Messier globular clusters in this constellation. In the summer of 1938 a nova was detected in M14, an extraordinarily rare event in a globular cluster. The nova was discovered only in 1964 on old photographic images.
