The Bubble Nebula, imaged with narrowband filters and processed using Ha as a "luminance" channel. Red is 76/24 Ha and SII, Green is OIII, and Blue is 85/15 OII and Ha. Each channel was then multiplied by the Ha data after stretching it all, and the hue adjusted in Photoshop to produce more natural-looking colors.
