NGC 2356

NGC 2356, VII 6, GC 1509

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

NGC 2356 is most likely NGC 2355 with a 10 arcmin error in declination. There is no other group of stars in the area that fits WH's description "A pretty rich and compressed cluster of stars" as well. JH did not see NGC 2356, but found NGC 2355 easily. Note, too, that WH's position for N2355 is about 1m 40s too far west; Dreyer discusses the circumstances of WH's observation of N2355 a bit more in his 1912 edition of WH's papers.
