Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "a small cluster of pretty compressed stars of various sizes, not very rich."

Examining 10 stars in the cluster, they determine its distance as 4.15 kpc; "this places NGC 2414 in the outer spiral arm +II"
The RNGC (Sulentic and Tifft 1973) notes that this is a 8.0 mag open cluster.
Trumpler (Lick Obs Bul, Vol 14, No. 420) gives the diameter as 8' and the class as 1 3 p.
AJ Crayon, using an 8" f/6 Newtonian, notes: "is an open cluster. It is 3' has an 8m star involved in 3' glow containing 5 stars of 11m, there is a 3' chain of 3 stars to the north northwest and another 3' chain of 4 stars going south from east edge, at 100X."
Steve Coe, in SACNEWS On-Line for February 1996, writes: "NGC 2414 is bright, pretty large, not compressed, 22 stars counted at 100X. This cluster consisted of three star chains and an unresolved hazy background. See this nice cluster at 7 hr 33.3 min and -15 27."
Steve Coe, observing with a 13" f/5.6, notes: "Bright, pretty large, not compressed, 22 stars counted at 100X. This cluster consisted of three star chains and an unresolved hazy backround."
6-inch f/8 Newt: "A very poor cluster with 1 bright star - 8th mag - and less than a dozen 10-11th mag stars scattered to the west and north-west in an elongated area. Needs high power to bring up."
12-inch f/10 SCT (76x, 218x)
Very much a dainty elongated group in a N-S curved direction. A string of 12-13 magnitude stars shape in a neat little string with member on the western and eastern sides. Double variable star 8.4-magnitude HD 60308 is situated inside the cluster just east of the string.
Observing site: Little Tycho Observatory
[7h 33m 18s, -15° 27' 0"] A bright 8mv star with 4 9.5-10.5mv stars around it, and some fainter ones barely glimpsed. Hardly a cluster. A degree south west of M 47.
