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

NGC 1499 is the brightest part of the very extensive California Nebula, so called since its outline more or less resembles the outline of the state. Barnard's position -- apparently sent to Dreyer in a letter, since it is not in any of his published notes -- is just off the nebula to its east. The position I've adopted is more or less the center of the brightest portion of the nebulosity on its northeastern edge.

Remarks

On the northern edge of the Zeta Persei Association lies the star Xi Persei, which seems to be the illuminating star for NGC 1499, the California nebula. On photographic plates it extends some 2.5 , but it is difficult visually. It was discovered by Barnard using a 6" refractor, and he described it as very faint, very large, extended North-South, difficult.

Modern observations

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "Very large! 2 degree x 1 degree extent; use binoculars or low-x, and N-filter; can even be glimpsed with the naked eye using N-filter; scan the area due N of 4M Xi PER; reference photo at VADSS-52."

Brian Skiff

Well, it was _discovered_ visually by Barnard, and shortly thereafter by another guy in Europe. So there's at least three visual naked-eye observations: Scotty Houston, me, and now Dave K. Probably lots of others we don't know about.
