Orange, no companion noted, the delicate double Σ 196 is 3' south
Oddly HR 577 is listed in WDS as the D component of Σ 196 when in fact this 6th magnitude star is much further away than the 9/10th magnitude pair with a parallax of 9.4mas compared to about 15mas for the WDS A and B components

150mm f/17.6 refractor by Tully 1827
A quadruple star, in mid-distance between α and γ, under the Ram's ear, lying nearly at right angles with the vertical. A 6, topaz yellow; B 15, deep blue; C 10, lilac; and D 9, pale blue. This is an exquisite object, of which the three southern members form No. 196 of Σ.'s grand Catalogue, under these measures:Pos. AB 53°.53 Dist. 2".370 Ep 1832.42This group is most difficult to observe, and the results are rather estimations than measures, particularly those of AB. Still, under every disadvantage, it forms an admirable test to try the light and distinctness of a telescope.
