Scope: Megrez II 80 mm at f/4.6, Location: Dos Picos Park, Ramona, CA 7 July, 2007, Camera: Artemis285
Exposure: 5 x 420 sec H-Alpha (1x1), 6 x 60 sec RGB Exposures (2x2).
Processing: Images were captured with Artemis Capture (as FITs). Aligned/stacked in Registax 4 and saved as FITS. H-Alpha and Color channels were scaled and color balanced in Astroart. Channels were co-registered in Astroart. Curves and Levels applied in Photoshop to the Luminance construction to optimize object features. Luminance construction consisted of the H-Alpha exposure. Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB). Color adjustment made to correct the color shift created by Luminance application. A light background noise filtering was applied with PixInsight LE SGBNR. Selective sharpening was applied to nebula features in Photoshop with a layer mask. Final Image size is approximately 1392x1040.
