and NGC 7605 = NGC 7583 were found by Marth late in 1864. There is
nothing in his places that he could have seen with Laselle's 48-inch
telescope, but just one minute of time preceding is a pair matching his
descriptions and relative positions. It happens that he had found the
brighter of the pair earlier in the same year. Thus, that object has two
entries in his list, and two NGC numbers.
Unfortunately, CGCG put the number 7583 on the fainter of the galaxies, though
it does in fact belong to the brighter.
