A free mod for Mass Effect 3, by CreeperLava.

The textures used in the galaxy map are very pixelated when you zoom in, and it looks very ugly. There is no way to fix this, but with this mod you can fix the textures used in the galaxy map, by upscaling them to make them look more realistic. This will help you to distinguish between planets, stars, and other space objects more easily.

This mod was inspired by Hubble pictures, and originally intended for the galaxy map in ME.

The following screenshots are a comparison between the original Hubble/telescope image, my edited version of it, and the vanilla texture.
