ALL THINGS COME TO AN END, even the largest of the constellations. This chart depicts the tip of Hydra's tail; the whole constellation spans more than a dozen Uranometria maps.

FEATURED OBJECTS: NGC 5247, NGC 5260, ESO577-PN024, Arp-Madore 4, IC 972.

NGC 5247
ESO577-G014
RA 13:38:03
Dec -17°52.9'
Galaxy

Discovered in 1785 by William Herschel (H II-297) "pF, L, mbM."

Houston estimates the visual mag of this galaxy as 12.0 using a 10-inch scope. He notes: "Hoiwever, the rather large size of this object, about 4' across, maded the estimate difficult." The larger NGC 5170 lies to the west.

Tom Lorenzin: “11.9M; 4.5' x 4' extent; fairly large, diffuse, not-quite-round glow surrounds somewhat brighter center; no nucleus apparent; just a few minutes SW of an uneven quadrangle of two 9M and two 10M stars.”

This object is mentioned in Abell G O "Globular Clusters and Planetary Nebulae discovered on the Natioanal Geographic Society - Palomar Observatory Sky Survey" (1955) PASP Vol 67 No 397 p258. He notes that object No. 26 in his list is IC 972, and has not previously been recognized as a planetary ... "These are all nebulae of comparatively low surface brightness."
