Host has green blob - real or artifact?

• by JeanTate

  The host of this #double is (I think) zph 0.511±0.036 SDSS J210541.09+025802.6, and it has a green blob at ~50 degrees (up 0, right 90):

  

  I think it may not be real because the nearby STAR SDSS J210539.82+025804.3 has a red blob (left); and somewhat more distant STAR SDSS J210543.78+025827.3 a green appendage (right, this may be partly due to the diffspike):
