Universe cosmic web

i’ve to recreate the cosmic web of the universe. Each colored pixel represents a least one galaxy, that’s around 300 million’s. I am trying to create a VR camera flight through universe, galaxies, star systems and end up on a planet. All i have to do is, add correct lights from stars and add nebula’s and make it look pretty.

This is prototype of a simple galaxy, around 1 million stars in this system. It does not look nice yet, i have add more details like nebula’s and supernovas.
