Messier 101: Lonely Spiral
Image data retrieved from the ESO dss archive. I had to correct the red exposure by rotating it counter-clockwise. I used the blue exposure for the blue (240), an artificial layer (blue+red)/2 for the green (120), the red exp. for the red (0) and the infrared exp. with a hue of 40 (don't know why...). The result wasn't bad in my opinion. Programs used: FITS Liberator and Photoshop CS.
