Description:
Another globular between Ascella and Kaus Australis I
have observed that night, quite bright and mid-sized.
It reminds a lot to nearby M 70 in brightness, size
and light distribution; it is just a bit brighter. At
any power I didn't see any traces of individual stars,
not even the grainy texture. Averted vision helps in
observing this cluster just to see how it fades out
relatively slowly. Central brightening is weak, but
obviuos. There is a bright star near the cluster.
