Bright SDSS host, no WISE one

The FIRST source on the S border of ARG0001t3w is elongated, possibly an #hourglass (NED lists it as two separate FIRST sources, FIRST J125135.4+283425 and FIRST J125135.5+283412):
The host is zsp 2.462 QSO SDSS J125135.43+283420.2, with an #outflow?:
It is a faint source in WISE bands 1 and 2, absent in 3 and 4 (can't post WISE images, anyone?).
That makes this a pretty unusual source, doesn't it? AFAIK, QSOs are nearly always quite bright WISE sources, compared with SDSS. Perhaps the reverse here is due to the really strong Ly-alpha emission, with a quite blue continuum ...

Here's Wise Band 1, Wise lime green, First red.

Very nice, thanks Chris! 😃 I particularly liked your choice of WISE Band 2 color (sage); pity there are colors called "guru", or "shrewd", or "perspicacious" ;D

The WISE canvass in ARG0002jxz is unusual (dark, almost black), and there's no apparent WISE source at the location of the #compact FIRST radio source. There is, however, a strange purplish SDSS one, zph 0.776±0.195 SDSS J105032.74+164859.7 (a purple pea? very likely a QSO):
However, there is an obvious, corresponding, WISE source, in bands 1 and 2 at least.
