M68 is a small-scaled globular cluster hided in the body of Hydra. Though the cluster belongs to a constellation of Hydra, it's easy to search it from stars of Corvus. M68 can be found by stretching the eastern edge of square of Corvus southward. The cluster is very sparse; you can detect individual stars only with small telescopes.
