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.
