Data: mag 3,7v  size 36'
Position: RA :  DEC :
At 131x magnification Omega Centauri presents a magnificent view. It is difficult 
to say how far it extends from its center but, at 244x the cluster does fill 
the whole FOV of the eyepiece with hundreds of stars. The dense center looks 
like innumerable little gemstones on a ball of silvery satin. Just N of the 
center seems to be a “hole” with fewer stars extending about 2x3’.The cluster 
is very dense but not as concentrated as M3.
