NGC6388, is a globular cluster located 1.7° south of Theta Scorpii. Dreyer's description reads very bright (mag. 6.8), large (8.7'), round, fairly gradually, then fairly abruptly very much brighter middle, well resolved, stars of magnitude 17 and fainter. Others claim the cluster's brightest stars are mag. 14.8. A good object for a large instrument. Smaller telescopes will enjoy the rich field. Image from the Digital Sky Survey.
