Description:
At 50X, M22 appears only about 14' in diameter, indicating there
is some haze on my southern harizon allowing me to only view the 
inner portion of theis GC. The cluster is tightly packed. Many
of the outter stars are resolved. It seems most of these are on 
the southern edge and are of 12 or 13 magnitude. The core remains 
as an even glow.
