In Scutum Sobieski is situated a remarkable and very extensive Nebula, known as the "Horseshoe," from its peculiar shape: from Sagittarii it lies N. by E. about 5° distant, in R.A. 18h. 13m. 308., Decl. 16° 15′ S. In Sagittarius is a globular cluster of very 9 P.M. Midnight.

S. 24° 56'. Owing to its great southern declination, there is but little chance of seeing this Nebula, except when southing. On the 19th it souths about half an hour after midnight, and, as about this time there is no Moon, may be best observed. |
