Ordered BGO to image GSC 00578-1121 so to get photons for κ Piscium. I had not seen the C companion of this triple star system with my C8 on 4 Sep '19.
Luminance only, 1 second subexposures, 12 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.
B is the obvious bright star to the north, the closest bright star.
Do you see it. Between, in the middle, is C. It is extremely faint. This matches the visual appearance in SkyTools where the point is rendered at magnitude 15.1! This is further supported by the mag 15 values of surrounding faint field stars.
What means the data in the WDS is wrong. I should submit a notice....
The page at Wikipedia describes it as a "solitary" star. I'll have to fix that...
