Corwin's Notes

===== NGC 7613 and NGC 7614 are two of Brother Ferrari's nebulae announced by Father Secchi in AN 1571. N7614 is "Very near with the 3rd object [N7613] south- preceding" according to the note that Secchi gives, but there is no obvious double nebula anywhere near the nominal position. There are many galaxies in this area, however. Perhaps one of them, plus a faint star or asterism, will turn out to be the objects the good brother saw. See NGC 7667 for more about these observations. ----- The faint galaxy (V = 16.5) with an eccentric nucleus at 23 19 51.7, +00 25 21 has sometimes been taken as NGC 7613. While Brother Ferrari called his object "vF", I do not think that it would have been visible in the 9.5-inch Merz refractor at the Roman College. JH, for example, called NGC 7615 "eF, eS" with his 18.7-inch reflector on a night with the "sky clear" and measured a good position for it. Nevertheless, d'A, Schultz, and Tempel failed to find JH's nebula which is nearly 2 magnitudes brighter (V = 14.8) than this galaxy supposed to have been seen by Brother Ferrari. See NGC 7667 for more on the Vatican observations. Still, to be inclusive, I've listed it in the position table -- with a couple of question marks appended, of course.
