Technical Notes:
Individual exposures were obtained using CCDAutoPilot2 and then sigma combined. The RGB image was created in Registar 1.0. A high-pass filter of 4 pixels was applied to the bright portions of the luminance image. A Gaussian Blur of 1 pixel with a threshold of 0 was applied to the dim portions of the luminance and the RGB image. Mild gradients were removed with Russell Cromaan's GradientXTerminator plug-in for Photoshop. The RGB image was duplicated and combined with the original using Soft Light to enhance color.
