  2. Deep Sky This Month – July 2018 (Ophiuchus: The Globular Bearer - Part 1 of 3)

    I hope that caught your attention! Of course, in reality, Ophiuchus is the Serpent Bearer or Serpent Holder. But, I like the name I have given, because it holds within its borders a total of 21 globular clusters with an apparent magnitude of less than 11.0. In addition it has four more that range from 11.55 to 14.0 in magnitude. Yet, even with such an impressive roster of globulars, it still has to play second string to Sagittarius, where one can find a total of 21 of these orbs under

    (continued from Part 1)

    With our basic background data in place, let’s begin our journey through the brightest globulars of Ophiuchus. Using Chart 2 below, we will start at 2.8 magnitude Delta Ophiuchi (Yed Prior) and 3.2 Epsilon (Yed Posterior). From Delta we will sweep northeast for 5.5° to pick up 5.9 magnitude 12 Oph. From here we slip just north of due east for another 2.75° to reach Messier 12 (NGC 6218, mag=6.1, size=15.0’, class=9). This is a large and showy cluster, and ...

    (concluded from Part 2)

    We now will reference Chart 5 below for our final run. From Theta we will move 1.25° to the northeast to 4.2 magnitude 44 Oph. Again moving slowly we head ENE for about another 1.25° to pick up 51 Oph at mag 4.8. Slip slowly eastward for almost 1.5° to try and pin down our first cluster on this leg, the small, but bright glob, NGC 6401 (mag=7.4, size=5.6’, class=8). It may exhibit some slight core brightness, and two or three foreground stars involved
