History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

IC 1470 is an HII region exactly at its discovery position. It was found nearly simultaneously by Spitaler (20 March 1892), Pechule, and Barnard (both 21 March 1892) while they were observing Comet Dennison (1892 II). The nebula has been incorrectly called a planetary nebula, and the IC number has also been incorrectly assigned to a much larger, much lower surface brightness diffuse nebula nearby.

Modern observations

Walter Scott Houston

Houston notes that this object is now regarded as a diffuse nebula, though at one time it was thought to be a planetary. Houston writes: "Using a pair of 5-inch binoculars, I searched quite a while before locating this faint object, which is only about 1' across. But once found, it was relatively easy."

15cm - not terribly obvious: a sm modhisfcbr spot @ 80x. filters somewhat helpful, but not greatly. 140x: sm 40" neb lies mostly S of embedded m11.5 *. close pair of sl brtr combined brtness ~3' W. BS, 12Jul1988, Anderson Mesa.

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.3M; 70" x 45" extent; faint and small; surrounds 12M star; 15' SE of DBL ST ADS 16481 (34" separation; 6.9-9.3M)."
