Lewis Swift discovered IC 1702 = Sw. XI-20 on 12 Oct 1896 and reported "eeeF; pS; lE; bet 2 st in meridian; wide D * nf; ee diff." His position is only 5 seconds of RA too far west and the description matches the field perfectly.

600/800mm - 24" (9/8/18): faint to fairly faint, moderately large, slightly elongated N-S, 50"x40", very diffuse. A mag 13 star is close off the north edge [45" from center].
