I personally have dual 1920x1080 monitors. I would love something that would connect on both (so two 1920x1080 ones together) but if not then I think for most people 2560x1800 is usually the most you need.
I like how there's noticeable distance between the galaxies, especially the two nearest to the front. That's usually hard to estabish since most real galaxy photo's we have to get ideas from seem rather flat (considering the fact they are just zoomed in from a great distance ) Makes me think of a young universe, where everything was closer together
pretty sure you're actually a time lord and simply went to a place in space and time where this was happening to take a picture. then you came back here and uploaded it as art instead of photography, since nobody would believe you if you said you used a camera.
