OBSERVING To celebrate 20 years of Sue French's stellar contributions to Sky & Telescope, we will be sharing the best of her columns in the coming months. The three Berkeley clusters above are from Setteducati and Weaver's list of 59 "obvious clusters." Messier 29, Berkeley 86, and Berkeley 87 are generally thought to be concentrations in the Cygnus OB 1 association, a loose stellar grouping that extends across 4° x 3%° of sky and is dominated by massive young stars.
