150mm f/17.6 refractor by Tully 1827
A close double star, over the Argo's stern, rather more than 2° north by east of the last object. A 7½, pale yellow; B 9, light blue. This fine object is No. 55 Officina Typographica, an asterism which Bode proposed to make by gathering 100 of the informes between Sirius and the hind legs of Monoceros, in commemoration of the art of printing. It must have been seen by Piazzi, who made this note to the principal star: "alia 9æ magnit. præcedit ad austrum;" for though this implies an error of quadrant, such error is readily made. It has been measured by Σ., with these results:Pos. 17°.8 Dist. 3".30 Ep. 1835.24
