As to how bright the quasar needs to be to shine through? It's practically a point source of light. If you're telescope can resolve enough detail, it doesn't need to be extraordinary in brightness. Basically it should look like what we're seeing.
I agree, but there's two things I'm not understanding, why can't we resolve individual stars in the same image while the point source of the quasar is resolved. And how come the quasars' spectrum is not reddened (not the same as redshifted, only a "dimming" of the "blue" frequencies)?

The image shows structure in the galaxy core, I suppose either dust lanes/clouds or lanes of such large numbers of stars that we can't see the individual sources. Isn't it the same as a screen of light for anything behind it?
If you want to answer in the "Big Bang Refuted" thread that's ok, this isn't very focussed on EU any longer.


Cheers.
