NGC 6642 is a tiny globular star cluster that lies within one degree of the always stunning M 22. This diminutive globular lies at a distance of 25,000 light years, 2.5 times farther than M 22. Yet, M 22 appears 21 times larger! Therefore, our little globular cluster isn't just farther away, it really is smaller and fainter. At low power this cluster may appear starlike. For best results use high magnification on a night with steady seeing.
