Position: RA 18h:10'  DEC -31 deg:46'
Description:
Very faint globular, pretty large (larger than nearby NGC 6569), very low in the
sky, hard to find becouse I'm not used to the telecope. Looks a bit asymetric,
it hasn't got a starlike core. The nuclear region is barely visible and it's
surrounded by a large, faint halo. It's in the center of a "G" of stars, having 
2 stars superimposed on it, the one from the SW is brighter than the NE one, 
which is very faint.
