NGC 2403 is about 8 million light-years from our galaxy and bears a strong resemblance to M33. Equipment: Meade 14" LX200R/STL-11000M/Astrodon LRGB filters/Paramount MEF-ratio: f/9.5 Exposures: LRGB: L 18 x 10 minutes, binned 2x2: R 23 x 10 minutes: G 18 x 10 minutes: B 18 x 10 minutes: RGB binned 3x3 Date: February 24-25 and March 21, 2012 Location: Landers, California, USA Technical Notes: Individual expsoures were dithered using CCDAutoPilot2 and then sigma combined. The RGB images were combined in Registar 1.0. The luminance image was sharpened with a High Pass Filter using a Radius of 2 pixels, and selectively applied using a Layer Mask. Reduce Noise was applied to the dim portions of the RGB and luminance images. The RGB image was duplicated and combined twice with the original using Soft Light to enhance color. |
