NGC 2467 in Puppis



Scope: C8 at f/3.4,  Location: Dos Picos Park, Ramona, CA   13 April 2007,   Camera: Artemis285

Exposure: 8 x 360 sec H-Alpha (1x1), 6 x 120 sec RGB Exposures (2x2). 

Processing: Images were captured  with Artemis Capture (as FITs).  Aligned/stacked in Registax 4 and saved as FITS. Luminance,  H-Alpha  and Color channels were scaled and  color balanced in Astroart. Channels were co-registered in Astroart.  Central Gradient removal was performed in Astroart. Curves and Levels applied in Photoshop to optimize object features. Luminance construction consisted of the H-Alpha exposure. Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB) - G2V calibration factors were applied.  PixInsight SGBNR  noise reduction was lightly applied to the background . Selective sharpening was applied to nebula features in Photoshop with a layer mask.  Final Image size is approximately 1392x1040.
