IC 1056 = IC 1057. Swift found IC 1057 on 8 April 1888 and described it as "eF, pS, R; bet a pB * and a coarse D *, nearer the latter." Sweeping across the same area three months later on 4 July 1888, he found IC 1056: "eeF, L, R; forms an arc of a small circle with 2 sts; 3 pB sts nr sf in form of arc of a large circle." His positions (14 42 20, +50 50 05 and 14 42 03, +50 51 45, respectively; both for equinox 1890) are far enough apart, and the descriptions different enough that he thought the nebulae different objects.

However, both descriptions are correct. The "pB *" about five arcmin south- southeast of the galaxy, is the western-most of the "3 pB sts nr sf" forming an arc. Similarly, the "coarse D *" about three arcmin west, is the two stars with which the nebula forms a smaller arc.
