Historical observations
William Herschel (c.1784)
Synonyms:H VII-060
Discovered in 1790 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "a large cluster of cL stars, pretty compressed and very rich, iR, 7' diameter."
Published comments
Trumpler, R.J. (1928)
Trumpler (Lick Obs. Bulletin, Vol 14, No 420) gives the diameter as 9' and the class as 2 2 m. He notes that it is markedly unsymmetrical.
Sulentic & Tifft (1973)
The RNGC (Sulentic and Tifft 1973) notes that this is a 9.0 mag open cluster.
Modern observations
Ancient City Astron.Club (1980)
Listed by the Herschel Club, described as "counted 40 stars, slightly loose grouping outwards from a compact nucleus, well defined. 8-inch, 48x."

"NGC 1513 is a most interesting mid-sized open cluster with a myriad of dim stars. For the lack of being able to describe it better, the cluster looks like two breasts. That is, two bags of stars (I believe pointing SOUTH) the easternmost bag is simply a circle of dim stars with a dim star inside as well. The westernmost bag is more irregular shaped. Both are connected on the North side. While I did not confirm this, I think it probably is best in larger aperture because of the lack of bright members."
Tom Lorenzin
Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "9M; 12' diameter; large, very rich, and much compressed; 40-plus 11M and dimmer members."

Telescope: C-8
[4h 10m 0s, 49° 31m 0s] 6 9-10 mv stars surround by a nebulous glow, which might just be the milky way. Not a great sight, on this moonlit night.
