Tonight I took a look at this beautiful globular cluster with my wife's C8 from our very light polluted terrace west of Madrid, Spain. Using a 12 mm Delos, which gives a magnification of 169x, I was able to resolve the cluster to the center. With a 7 mm Nagler (290x) the cluster was completely resolved as well, though the stars were harder to see due to seeing and the relatively high magnification.
