150mm f/17.6 refractor by Tully 1827

A pair of stars [with 56 And] between the Triangle and the Lady's right knee, both of the 6th magnitude, and both yellow, being Piazzi's admirably observed Nos. 203 and 204, Hora 1. These stars are suspected of physical connection, principally on the ground that their identity of movement in space implies their union in some vast system. Their proper motions have lately been rigidly inquired into, and the following results registered:
    B. No. 203 RA +0".06 Dec. -0".01
204 +0".24 +0".04

A. No. 203 RA +0".03 Dec. -0".02
204 +0".21 +0".01

[Gaia DR2 203 RA +0".009566 -0".004977
204 +0".183659 +0".011670]
This object is readily identified, by carrying a line from π Andromedae through β, and extending it about 10° beyond the latter; and it is also nearly in mid-distance between Al'mak and Mothallath.

[Given the Gaia DR2 difference in RA proper motions and a dramatic difference if parallax (2.88 and 9.88mas), these two stars are not physically related despite appearances]
