Scope: C8 f/5 Location: Del Mar, CA 11/18/2003 Camera: ToUcam SC3
Exposure: 6 x 150 sec exposure with H-Alpha filter and 18 x 33 sec exposure with IR block filter for Luminance . 15 x 20 sec RGB Exposures
Processing: Captured and stacked in K3CCDTools with HA,IR,R,G,B saved as FITs. HA and IR exposures were combined in Photoshop for Luminance channel; Some HA exposure was mixed in with the Red channel. LRGB masters were co- registered in Astroart. Some Lowpass filtering was applied followed by un-sharp mask on the Luminance frame. LRGB combine was done in Photoshop using Luminance Layering . Ears were removed with Loreal; background was smoothed in SGBNR as saved as TIF. The result TIF had minor touch up in Photoshop.
This image was taken in my front yard in Del Mar there is a fair amount of light pollution here. The 10nm bandwith H-Alpha filter was able to pull some contrast out of the sky glow. The image below was processed without mixing any of the HA exposure into the Red channel. Horizontal FOV is 16'
