This globular cluster is the third brightest in the sky and
can be seen with the naked eye on a dark night.
It would be brighter still were it not partially obscured by interstellar dust.
M22 was probably the first globular cluster ever discovered.
It is one of the most beautiful globular clusters and
begins to resolve well in small telescopes.
Larger in size than the better known M13, M22 is not as favorably positioned for northern observers,
lying low near the horizon.
Because it sits less than one degree from the ecliptic,
M22 is frequently in conjunction with the moons or planets.
Through any instrument, this burning ball of half a million stars is a stunning sight.
