NGC 1650 = PGC 15931)
Discovered (Nov 12, 1885) by
Francis Leavenworth
A 13th-magnitude giant elliptical galaxy (type E4+) in Eridanus (RA 04 45 11.4, Dec -15 52 12)
Per Dreyer, NGC 1650 (= Leavenworth list I (#137), 1860 RA 04 38 40, NPD 106 09.5) is "very faint, pretty small, extended 0°, bright middle nucleus". The second IC lists a corrected RA (per Howe) of 04 38 52 and adds "2 others suspected 3 arcmin southeast and northwest, the latter probably 2 extremely faint stars". Based on a recessional velocity of 10790 km/sec, a straightforward calculation indicates that NGC 1650 is about 500 million light years away. But for objects at such distances we should take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the galaxy was about 480 million light years away at the time that the light by which we see it was emitted, about 490 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 2.3 by 1.3 arcmin, the galaxy is about 320 thousand light years across.

NGC 1671 (probably not =
IC 395 = PGC 16095)
Recorded (Oct 2, 1886) by Lewis Swift
A lost or nonexistent object in Orion (RA 4 50 16.5, Dec -00 46 12)
or a 13th-magnitude lenticular galaxy (type SB0?) at RA 04 49 33.8, Dec +00 15 12
Per Dreyer, NGC 1671 (Swift list V (#63), 1860 RA 04 43 09, NPD 91 00.9) is "pretty faint, pretty small, round" (Swift's Catalogue No. 5 note adds "pretty bright star near to southwest"). The position precesses to RA 04 50 16.5, Dec -00 46 12 (whence the position above), but there is absolutely nothing there, nor anywhere near there. Corwin states that whatever Swift thought he saw is probably lost or nonexistent, but mentions the possibility that NGC 1671 might be the same as IC 395, then rejects the idea because it would require a huge error in position (43 seconds of time in right ascension, and more than a degree in declination) that cannot be explained in any reasonable way. However, the description of NGC 1671 fits IC 395 as well or better than its own description, and as a somewhat surprising result the identity of the two listings has been almost universally accepted. So although I agree with Corwin's conclusion that NGC 1671 is lost or nonexistent, its possible identity with IC 395 has to be mentioned for the sake of completeness, no matter how unwillingly.

NGC 1673 (in the Large Magellanic Cloud)
Discovered (Dec 23, 1834) by
John Herschel

Apparent size 0.70 arcmin.

NGC 1674 (associated with
NGC 1675)
Recorded (1886) by Gerhard Lohse
A lost object or part of a group of stars in Taurus (RA 04 52 25.0, Dec +23 51 37)
Lohse identified this as one of two faint nebulae in Taurus, the other being listed as NGC 1675. Nothing exists at Lohse's recorded position, and the nebulae should probably be considered lost or nonexistent. However, there is a tentative identification of a small stellar group at the position listed above as something that might correspond to Lohse's observation. If that is correct, then the single group would correspond to both of Lohse's nebulae, hence the identical position listed for the two NGC objects.
