Corwin's Notes

===== NGC 1340 is certainly identical to NGC 1344, just as Dreyer first suggested in the NGC note. Swift looked for it with his 16-inch from Lowe Observatory on Echo Mountain but could not find it. He wrote that it should be "struck out" in a note appended to his third list of new nebulae found at Lowe. As Dreyer notes, JH saw this in two different sweeps, but only crudely estimated the position in the first of those (JH says "Transit missed while observing another nebula"). That estimated position was far enough off that when he was assembling his CGH table of nebulae back in England, he thought he had two different nebulae. Lacking any other evidence, he took a rough mean between his position and his father's for NGC 1344. And there is another tale to tell. WH used a star he called "12 Eri" as the reference star for his offsets for the galaxy. I depend on "Sky Catalogue 2000.0", Vol. 1, for Flamsteed numbers, so was not happy to find no listing for "12" Eridani (11 and 13 are there, but not 12). A search based on WH's offsets and the modern position for N1344 shows that 12 Eri is probably alpha Fornacis. But this position is 20 seconds and 10 arcmin off JH's for N1340 -- no wonder he thought there were two nebulae here! In any event, there is only one. Its RA is close to that for NGC 1340 and its Dec is close to that for NGC 1344. Sometimes, it just takes teamwork to get things right.
