Technical Notes: Three exposures for each color were taken through a diffusion filter, which both enlarged the images and enhanced the colors of the bright stars. A second RGB image was created using these exposures, which was digitally composited with the luminance and unfiltered RGB exposures using the Lighten function in Photoshop CS2.
Russell Croman's GradientXTerminator plug-in for Photoshop was used to remove light pollution gradients.
