Technical Notes: Individual exposures were dithered using Paul Kanevsky's AutoDither plug-in for CCDSoft,
and CCDAutoPilot2, and then sigma
combined. The RGB image was created in Registar 1.0. A copy of the RGB image was combined
with the original using Soft Light to enhance color saturation. The luminance image was
copied twice and a High-Pass filter of 2 pixels and 4 pixels selectively applied to one
copy each.
