IC 2855 is a tiny blue galaxy with a relatively very bright blue knot on the northeastern side. There is a double star superposed on the western side. I'd be suspicious about the classification of these two objects as stars if the southeastern of them did not have an SDSS spectrum showing it to be an F9 galactic star with a radial velocity of -20 km/s. As the other star appears to be virtually identical, I have little doubt that it, too, is a superposed star.

(The double star is Gaia DR2 3914559950944972160 and Gaia DR2 3914559946653419136)
