Leo is one of the
most prominent constellations of the zodiac. Its brightest star, Regulus, is very near the
ecliptic, so it often forms conjunctions with the Moon and planets. Saturn is the bright
yellow object at lower left.

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.
