IC 2050 (= PGC 14704 = PGC 429559)
Discovered (Dec 7, 1899) by
DeLisle Stewart
A magnitude 13.7 spiral galaxy (type SAB(rs)bc? pec) in Dorado (RA 04 13 56.1, Dec -53 28 32)
Historical Information: Per Dreyer, IC 2050 (DeLisle Stewart #276, 1860 RA 04 10 32, NPD 143 49) is "faint, very small, considerably extended 60°". The position precesses to RA 04 13 55.7, Dec -53 27 48, only 0.7 arcmin north of the galaxy listed above, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Based on a recessional velocity relative to the Cosmic Microwave Background radiation of 12350 km/sec, a straightforward calculation indicates that IC 2050 is about 575 million light years away. However, for objects at such distances we should take into account the Universal expansion during the time it took their light to reach us. Doing that shows that the galaxy was about 545 to 550 million light years away at the time the light by which we see it was emitted, about 560 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and its apparent size of 1.05 by 0.75 arcmin (from the images below), it is about 165 to 170 thousand light years across.

IC 2051 (= PGC 13999 = ESO 004-007)
Discovered (December, 1900) by
DeLisle Stewart
A magnitude 11.5 spiral galaxy (type SAB(rs)bc? pec) in Mensa (RA 03 52 00.8, Dec -83 49 51)
Historical Information: Per Dreyer, IC 2051 (DeLisle Stewart #268, 1860 RA 04 10 41, NPD 174 14) is "a remarkable object, very faint, very small, stellar nucleus, elliptical ring". The position precesses to RA 03 51 53.2, Dec -83 50 48, less than an arcmin south of the center of the galaxy listed above and barely outside its outline, the description fits and there is nothing else nearby, so the identification is certain.
Physical Information: Based on a recessional velocity relative to the Cosmic Microwave Background radiation of 1785 km/sec (and H0 = 70 km/sec/Mpc), IC 2051 is about 80 to 85 million light years away, in good agreement with redshift-independent distance estimates of about 55 to 95 million light years. Given that and its apparent size of about 2.9 by 1.55 arcmin (from the images below), it is about 70 thousand light years across. The galaxy has a complex inner structure, with a central ring, a nearly stellar nucleus (as stated in the NGC/IC entry) and considerably evidence of dust lanes near the nucleus, suggesting that it is a starburst galaxy.
