2MASX J16584721+6256245 source among others guesses of FIRSTJ165848.5+625546?

ARG00001ks

FIRSTJ165848.5+625546 is close to AGN mentionned but there is another north side lobe not in line with the two former.

I wonder if an intermediate source is more appropriate like SDSS J165843.52+625648.9. Does not explain the bright blob in north right?

What do you think?
