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.
