Pelican Nebula IC 5070



Scope: Megrez II  f/4.8 Location: Laguna Mountains, CA   2 August 2008  Camera: Artemis285

Exposure: 8 x 8 min H-Alpha,  8 x 2 min RGB Exposures

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 in LAB color Space.   A light background noise reduction was applied in PixInsight LE (SBNR).  A light sharpening was applied to nebula regions.  Final Image size is approximately 1392x1040.

All exposures in this image were guided; North is up in this image.  IC 50 70 is referred to by common name of the "Pelican Nebula" due its distinctive shape in the form of a pelican profile. Its distance to Earth is estimated at 1,800 light years. This image replaces an earlier image that can be seen in the Archives here.  The Vertical FOV is 82'.
