Scope: C8 203mm  at f/3.6,  Location: Laguna Mountains, CA  9 September,  2007,   Camera: Artemis285

Exposure: 9 x 8 min H-Alpha (1x1), 8 x 1.5 min RGB Exposures (2x2). 

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.  Luminance construction consisted of the H-Alpha exposure.  Curves and Levels applied in Photoshop to the Luminance construction to optimize object features.  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 reduction was applied in PixInsight LE (SBNR)  Selective sharpening was applied to nebula features in Photoshop with a layer mask.  Final Image size is approximately 1044x1392

 North is up in this image. This is an object cataloged as IC 1795 and is located in the Constellation of Cassiopeia.  This region is also referred to occasionally as NGC 896. It is not clear to this observer the exact objects in this field that  belong to the NGC 896 catalog reference. This area is an emission nebula complex part of a much larger emission complex known as the "Heart Nebula". This image replaces an earlier image that can be seen in the Archives here .   The Horizontal FOV is 36'.

Image center is located approximately - Equatorial 2000: RA: 02h 26m 45s Dec: +6203'07"
