CED 214 in Cepheus - Cassiopeia



Scope: Megrez II 80 mm at f/4.3,  Location: Laguna Mountains, CA  11 August,  2007,   Camera: Artemis285

Exposure: 8 x 480 sec H-Alpha (1x1), 6 x 90 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 1040x1392

 North is up in this image. This is a hydrogen emission complex more commonly known as Cederblad 214 but it is also catalogued by Sharpless in his catalog as Sh2-171.  This field  is located on the border of constellations Cepheus and Cassiopeia. The central star energizing the hydrogen emission is a 5.7 apparent magnitude star.  This image replaces an earlier image that can be seen in the Archives here .   The Horizontal FOV is 67'.

Image center is located approximately - Equatorial 2000: RA: 00h 04m 42s Dec: +6709'59"
