Description:
Beautiful globular cluster, my favourite deep sky object, also first
I saw. On every magnification it is very well resolved. In the 
cluster there is almost circular formation and two radial rows of stars that
are brighter than others, but the brightest star in it is on the half
way between center and the cluster's edge. Field of view is filled 
with many stars, but only few of them are brighter than mag. 10.
