I used a public domain NASA image of the Horsehead nebula, removed the noise and errors and optimized the color range and saturation.

Special thanks to chriscologne for the idea of retouching astronomy photos. I used Photoshop CS3 and plugins to retouch the image.

I've been in love with the Orion Nebula by chriscologne for quite a while, so I made my own nebula, which I would have missed 'cause I'd be in cryosleep to, uhm, whereever I would be going. Or something... I don't know exactly.

Apophysis and loads of Adobe Photoshop CS4.

A nebula lost in the infinity.

Created in Adobe Photoshop.

This digital painting took what can only be described as a ridiculously long time to do. I hope you all like it. No stock or references of any kind were used.
