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.
