Two color quasar?

It’s a known QSO ( in Simbad 2MASS J09175053+2901369** – Quasar) But why two distinct color areas? Overlapping with another object ?

Nice find! Based on the Gaia observations (under the “Imaging catalogs” menu), it’s two objects, the red one with 0 motion, and blue one with significant proper motion (a foreground star).

Thanks a lot: just 0.9 arcsec separation!
