Jun 17, 1998    Yavapai Point, Grand Canyon National Park, AZ (map)
20cm f/10 SCT

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.
