CLICK ON IMAGE FOR FULL SIZE VIEW Scope: C8 203mm at f/4.2, Location: Laguna Mountains, CA 11 August, 2007, Camera: Artemis285 Exposure: 8 x 480 sec H-Alpha (1x1), 6 x 120 sec RGB Exposures (1x1). Processing: Images were captured with Artemis Capture (as FITs). Aligned/stacked and dark subtracted in Astroart with Sigma Combine. 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 1040x1392 North is up in this image. This is a hydrogen emission complex catalogued in the New General Catalog as a cluster as NGC 7380 but it is also catalogued by Sharpless in his catalog as Sh2-142. This field is located in the constellation of Cepheus. This image replaces an earlier image that can be seen in the Archives here . The Horizontal FOV is 36'.
