M70 (NGC 6681) -- Globular Cluster in Sagittarius
The globular cluster M70 is far down in the southern sky from where I live. The glare from
Washington D.C. and the local mall prohibits me from having good views of this Messier
Object from my house. A trip to the local astronomy club’s observing site, helps a great
deal. M70 has an intense and bright core. Only about 20% of the Milky Way’s globular
clusters have collapsed cores like M70. I find these globular clusters more rewarding
visually than those that consist of a more homogeneous spherical appearance.
I cannot resolve the stars within M70 in the small refractor. But its much brighter core is
easily seen at the eyepiece.
