Equipment: Meade 14" LX200R/STL-11000M/Astrodon LRGB filters/Paramount ME
F-ratio: f/9.5
Exposures: LRGB: L 18 x 10 minutes, binned 2x2: R 17 x 10 minutes: G 19 x 10 minutes: B 16 x 10 minutes: RGB binned 3x3
Date: April 22, 23, 29, and 30, 2011

Technical Notes: Individual exposures were dithered using CCDAutoPilot2 and then sigma combined. The RGB image was created in Registar 1.0. A high-pass filter of 2 pixels was applied to portions of the luminance image. Reduce Noise was applied to the dim portions of the RGB and luminance images. A duplicate of the RGB image was combined with the original using Soft Light to increase color saturation.
