NGC 6401 [SEP] constellation
NGC 6401
NGC 6401 is a globular cluster in the constellation Ophiuchus. William Herschel discovered this star cluster in 1784 with his 47 cm telescope, but mistakenly believed it to be a bright nebula. Later his son, John Herschel, was to make the same error because the technology of the day was insufficient to allow the individual stars to be resolved visually.
