    Real or CG you tell me.

    I'm just curious to see which you guys think is the real image and which is the one generated by galaxy evolution simulations.

    The colorful grain and lens flares tells u that left is real

    I would be very suprised if the real one turned out to be the right one. I would ask how that picture was obtained.

    So i say Left!

    edit: because left one looks more clear, but that sometimes means CG. But if the right one is real, then it's a crude photo

    I also think left is real.

    Many features in the right image are duplicated. Left is real.

    pretty simple none are 'real' as you can't see color in galaxies with visible light imaging you have to make 3 b/w images with different colored filters on each red,green and blue, then assemble in a paint app like photoshop.

    so none...all are photoshopped to some degree!

    both images are C.G (computer generated)
    the real one is a false color composite.

    show me the 3 b/w real images against the 3 b/w cg images and ask me again!

    before I read Cress' comment I was going to say why in hell would you want to copy so slavishly anything as artificial and contrived as a space photo, most of the gaseous stuff only ever shows up due to some kind of filtering that favours one wavelength or another anyway, and in light of the above written, why would you want to copy those lurid and oversimplified colours and that false chromatic aberration, I mean for what – so that you can produce an image that not merely looks as bad as the original but one that looks far worse.

    I understood this to be about form and not color ("galaxy evolution simulations").

    I'm going to buck the trend and say the right image is real, only because the left image is 'prettier' and makes me think it's an enhancement of reality. (That said, I think I'm wrong.)

    G.

    Edit: I just looked at some other galaxy 'real vs. sim' comparisons and, yeah, I think I'm wrong. The real images are much prettier than the sims (though I'm sure the 'real' images get quite a bit of enhancement anyway.)

    Its true that Hubble, Spitzer, Chandra and 'most' other satellites use only b&w imaging with various wavelength filtering. However the general point you are trying to make is absolutely false. You will not 'see' color in nebula's or galaxies till you have a mirror > 22". A mirror of >=24" finally opens the realm of galaxies (yes you can see a couple with the naked eye but most are small and dim after all they are just a little far aways) and galaxy color will start to be seen with mirrors > 34". Exception to this rule is M82 outflow which can be seen as a dim rust with a 24" mirror. Imaging can reduce that when using decent cameras and even better when chilled, either film or ccd. Normally an earth based scope will image with at least 3 filters and an rbg pass. Plus now a-days the rule of the roost is a ton of short exposures and then stake them. This trick always some pretty funky cool magic to happen for even the smallest scopes.

    The one on the left is real, the one on the right still looks a bit too artificial.
