ARG0002gar - not double lobe ...

... rather it's two separate z~0.64 giant ellipticals, possibly near the center of a rich cluster, SDSS J074234.97+182406.1 (center), and SDSS J074232.05+182437.8:
What I mistook for the core is, in fact, another galaxy - likely also a giant elliptical - in the same cluster, SDSS J074233.57+182423.6. So, if both 'lobes' have corresponding IR sources, perhaps it's more likely they're separate sources!
