20cm f/10 SCT

Apr 16, 1828    

A fine globular cluster, stars very small, of 12th to 18th magnitude, with one of 10th magnitude, and one of 10th to 11th magnitude; nearly round; very gradually pretty much brighter toward the middle, but does not come up to a blaze. Insulated; 3' diameter. It forms a link between I.70 [NGC 5634] and 10 or 12M [M10 or M12].

Charles Messier
Jun 5, 1764    

Nebula without stars, on the parallel of Antares between Scorpius and the right foot of Ophiuchus: this nebula is round; one can see it very well with an ordinary telescope of 3.5-foot; the nearest neighboring known star to this nebula is 28 Ophiuchi, which is of mag. 6, according to Flamsteed.
