LBN 437 in Lacerta



Scope: Zenithstar 66 mm at f/4.5,  Location: Tierra Del Sol (SDAA site), CA  10 September,  2010,   Camera: Artemis285

Exposure: 7 x 8 minutes Luminance exposures (1x1), 8x8 minutes H-Alpha (1x1), 7 x 3 minutes RG Exposures (2x2), 5 x 3 minutes B 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 blended with the luminance exposures.  Curves and Levels applied in Photoshop to the Luminance construction to optimize object features.  A light background noise reduction was applied to the Luminance construction .  H-Alpha was blended with the red channel 80/20. Final LRGB combine was done in Photoshop  using Luminance Layering.    A light sharpening  was applied to the final image.   Final Image size is approximately 1392x1040. (Cropped to 1367x1021)

 North is up in this image. This is a combination dust obstruction and faint hydrogen emission complex. The red areas are H-Alpha emission; the brown areas are interstellar dust. It is  catalogued by as a Lynd's Bright Nebula - LBN 437.  This region is located in the constellation of Lacerta.    The Vertical FOV is 105'.

Image center is located approximately - Equatorial 2000: RA: 22h 32m 10s Dec: +4036'05"
