Description:
One wonders why Messier did log this small cluster but did not register all the
similarly faint clusters in Oph or Sgr.M72 looks granular at 131x and resolves
into 2 dozen stars at 342x. The diameter appears to be some 5’. M72 has a loose
appearance and does not brighten much towards the center. Unspectacular Messier-
object.
