Equipment: Vixen
102-ED/ST-10XME/Astrodon LRGB filters/Paramount ME
F-ratio: f/6.5
Exposure: LRGB: L 8 x 5 minutes: R 8 x 5 minutes: G 8 x 5 minutes: B 8 x 5
minutes: RGB binned 2x2
Date: December 7, 2007
Location: Landers, California, USA
Technical Notes: Individual exposures were taken using CCDAutoPilot2 and then sigma combined. The RGB image was created in Registar 1.0. A Gaussian
Blur of 0.5 pixel was applied to the RGB image and to the dim portions of the luminance
and RGB images. Unsharp Mask of 1 pixel with a Threshold of 1 was applied to the bright
portions of the luminance image at 50%. The RGB image was duplicated and then combined
with the original using Soft Light to enhance color.
