Corwin's Notes

===== NGC 1440 = NGC 1442. WH's offset from 54 Eridani should be 1 deg 10 armin north rather than the 10 arcmin that he recorded for II 594. Though JH and Dreyer both noticed this, as did Auwers and Schoenfeld (see the GC and NGC Notes), they both also included both of WH's entries for the galaxy. JH has a curious note appended to his two observations of this in the CGH Observations: "N.B. Both observations agree in making the degree of PD 108 -- whereas it appears in the reduction of my Father's observations as 109." Taken at face value, it shows how obvious this particular error was. But it is recorded under h2583 = H II 458 which has the correct offset from its comparison star, 20 Eridani. As I noted, it is WH's observation for II 594 that is incorrect. So, even JH was somehow confused here. In any event, the galaxy has at least two NGC numbers and the identity is certain. By the way, this turns out to be probably also identical with NGC 1430 and NGC 1458. See those numbers for those stories.
