Equipment: Nikkor
300mm f/4 lens/ST-10XME/Astrodon LRGB filters/Paramount ME
F-ratio: f/5.6
Exposures: RRGB: R 8 x 20 minutes: G 8 x 5 minutes: B 8
x 5 minutes: RGB binned 2x2
Date: October 4, 2008
Location: Landers, California, USA
Technical Notes: Individual exposures were dithered using
Paul Kanevsky's Auto Dither plug-in
for CCDSoft and then sigma
combined. The RGB image was created in Registar 1.0. A high-pass filter with a radius of 4
pixels was selectively applied to a copy of the luminance image, while Reduce Noise was
applied to the dimmer portions of the luminance image and to the RGB image.
