NGC 105 (= PGC 1583)
Discovered (Oct 15, 1884) by Édouard Stephan
A magnitude 13.2 spiral galaxy (type Sab?) in Pisces (RA 00 25 16.9, Dec +12 53 01)

Per Dreyer, NGC 105 (= Stephan's list XIII (#4), 1860 RA 00 18 03, NPD 77 53.4) is "very faint, small, round, very little brighter middle". The position precesses to RA 00 25 17.2, Dec +12 53 10, within 0.2 arcmin of the center of the galaxy, so the identification is certain. Based on recessional velocity of 5290 km/sec, about 240 million light years away, in good agreement with redshift-independent distance estimates of 190 to 250 million light years. Given that and apparent size of 1.1 by 0.7 arcmins, about 75 thousand light years across.
