The whole cluster appeared clearly granular, the edge areas were very well resolved. Many individual stars were visible with averted vision close to the center. The edges appeared irregular due to star chains.

EASY
8" f/6, 37x, Bortle 4, NELM 6.0
Extremely bright center. Outer regions granulous. At 150x the cluster was resolvable close to the center, especially the outer regions. The center was still granulous.

EASY
80mm f/6.25, 20x, Bortle 6-, NELM 5.0+, SQM-L 19.6
Concentrated toward the center with radial star chains, so that the shape of the cluster appears irregular. At 50x there was an apparent star in the center with no stars in the direct vicinity (like a hole in the center).

EASY
4.5" f/8, 28x, Bortle 6-, NELM 5.0, SQM-L 18.9
Rather faint members. The cluster is more dominated by star chains, so it appears more irregular.
