Technical Notes: Individual exposures were dithered using CCDAutoPilot2 and then sigma combined. The RGB image was created in Registar 1.0. Russell
Croman's GradientXTerminator
plug-in for Photoshop was applied to the luminance and RGB images to remove mild
gradients. Reduce Noise was applied to the RGB image and the dim portions of the luminance
image. Gaussian Blur of 1 pixel was applied to the RGB image.
