Lewis Swift found IC 1671 = Sw. XI-18 on 18 Dec 1895 and recorded it as "eeF; vS; R; p 7m * nf 47 s; p of 2." There is nothing at his position, but IC 93 is 30 seconds of RA west and 2.3' N. Furthermore, a mag 8.4 star is 47 seconds of RA following, so the equivalence is certain. His comment "p[receding] of 2" should read "f[ollowing] of 2", consistent with his RA order.

400/500mm - 18" (11/13/07): fairly faint, fairly small, elongated at least 3:1 NNW-SSE, 0.7'x0.2', broad weak concentration. The tips taper, though there is a strong impression of irregularities at the tips. Forms a pair with much fainter IC 1667 4.8' W. The IC 1670 pair lies 15' N.

18" (12/18/06): faint, fairly small, elongated 5:2 NNW-SSE, 0.75'x0.3', weak concentration, slightly asymmetric appearance at the ends. IC 1667 lies 4.8' W. Located 11' W of mag 8.5 HD 8061.
