Category: Globular cluster.
Class: V
Constellation: Sgr
Data: mag 8.1  size 7.8'
Position: RA 18:43  DEC -32:18
Description:
In Sagittarius, halfway between the stars Ascella and Kaus Australis. I can also locate it with a line made up of stars SAO 210312, 210344, 210384 and 210478 (magv = 5,3, 6,9, 7,3 and 7,8 respectively). Less glittering that its neighbor, M69, M70 are seen as a very small fuzzy spot whose center does not show particular characteristics. The averted vision gives a little more shining to this globular cluster but the whole remains of modest size. Also, at position 7 or 8 hours, I perceive a second nebulous object, not far from M70. After checking, it was a small chain of four stars, magnitude between 10,2 and 11,0.
