This image of M3 was taken on 15 March 03 with nearly a full moon.
(20) individual subexposures of 240sec were guided with Star2000.
Color synthesis was done using Mike Smith's plugin for Astroart.
AIP4WIN was used to combine the individual color frames into a LRGB image.
The original LRGB image was balanced in Photoshop and then an additional
processed luminence frame was layered onto the original LRGB image to create
an effective LLRGB image.
