Active Galactic Nuclei - categorisation on the basis of observer?
Yes, but most probably not in your mentioned example.
You need larger distances to make a difference, I guess.
However, it is by now largely accepted a unification model for AGNs, where the difference are mostly due to the angle of line of sight.


First introduced by Urry &amp; Padovani, then developed for further observations.

Anyway, this is only half of the truth, since the AGNs evolve, and in this evolution feedback on the host galaxy is exerted. Also, the amount of feeding/obscuring gas is varying with time (redshift) and this has to be taken into account for a correct classification.
For the jets too, it is also possible that they forms only in certain stages of the AGN life...
As usual in astronomy, things are much more complicated than simple catalogs/models !
