Per Dreyer, IC 1671 (= Swift list XI (#18), 1860 RA 01 12 42, NPD 107 50.1) is "extremely faint, very small, round, 7th-magnitude star 47 sec northeast". The position precesses to more than half a degree east of the correct position, so its identity (and identification with IC 93) might never have been realized, save for one thing -- the star 47 sec northeast. Swift's earlier observation (which had an accurate position, and could be properly identified) had noted an 8th-magnitude star 46 sec east and 1 arcmin north. As explained by Corwin, the fact that both observations involve the same distance from what is undoubtedly the same star means that although the position measured for IC 1671 was very different from that for IC 93, they were actually the same object. (Note: Supposedly some catalogs list IC 93 and IC 1671 as separate objects, or IC 1671 as nonexistent; however, every reference I have seen shows them as being the same.)

IC 1698 is about 300 million light years distant, and 100 thousand light years across.
