This is a large and very bright globular with a round, blazing core embedded in a round, very bright and rich halo. Well seen at high magnification, the richness of the outer halo works against resolution; the stars are fairly tightly packed and very even in brightness, leading to a mottled appearance with resolved stars overlaid.
