Rich orange, a 9th magnitude companion is visible 1.5' southwest, Smyth describes the primary as "rose" and the companion as "light blue", more than a bit of fanciful vision here, Gaia DR3 measurements show this companion to be a background star

150mm f/17.6 refractor by Tully 1827

A wide pair of stars, in the asterism of Hercules, but on the shoulder of Serpentarius; it is south-west of Rasalgeti, at 8°½ distance. A 5, rose tint; B 9, light blue; a third and very minute glimpse-star in the nf quadrant. This object is 116 ♅. VI., and not 41 ♅. III. Under the latter head I should have concluded Sir William Herschel to have meant A, and the point of light in the nf, but that he has registered the components "both equal;" from which, and the result of the measures, it seems evident that 100 Herculis was the star observed in 1781, by Mr. Bryant, of Bath. The mistake occasioned this object to be placed on the working lists, and secured its being well attended to; and the following are the previous results:

    ♅.   Pos. 231° 12'  Dist. 74".62  Ep. 1783.44
    Σ.        230° 18'        83".70      1819.63
    H. and S. 230° 51'        80".09      1821.42
   [WDS       229°            84".1       2016]
