Small globular, very few stars resolved, or are they foreground? very compact, looked at it with the 28" [Dennis Young, Sedona] across the parking lot, very nice
Charles Messier
Aug 31, 1780
Nebula without star, near the preceding [M69], & on the same parallel: near it is a star of the ninth magnitude & four small telescopic stars, almost on the same straight line, very close to one another, & are situated above the nebula, as seen in a reversing telescope; the nebula was determined from the same star Epsilon Sagittarii.― Connaissance des Temps, 1781
