Quasar.

• by Mjtbarrett

  Well spotted Sven-Vdv! Good eyes 😃
  I think that this is a quasar called [VV 2006] J 164100.3+342815. The standard answer would've been that the optical effect is bigger because the star is brighter! In this case you've spotted a difference that has a cause...
  Nice find.
