This is my first experience of creating skybox textures, hope you will enjoy this.
Space Engine - Get the scenery
Paint.Net - Color correction
VTFedit - Convert to .vtf
Textures resolution: 2048x2048
If you want lower size version, just ask me
Installation: extract files to */Steam/SteamApps/Common/Counter-Strike:Source/cstrike/materials/skybox

Well when I download skyboxes I do it manually by guessing.
But judging from the first screenshot it should be similar to 15 45 0 or everything (without the roll) + 90, 180 or 270
