Aquila_Sagitta_Vulp_SoapS062311
Barnard 142 and Barnard 143 dark nebulae in Aquila in a rich summer Milky Way star field. B142 is in the center of the frame, and B143 lies below. Dark nebula are clouds of non-luminous dust and gas in space that obscure the stars behind them.
The distance to Barnard 142 is estimated to be about 2,000 light years. They are located about 3 degrees northwest of Altair, one of the stars in the Summer Triangle.
B142 and B143 get their names from Edwin Emerson Barnard's famous list of dark nebulae that he published in a paper in 1919 in the Astrophysical Journal,'On the Dark Markings of the Sky' with a Catalog of 182 such Objects.
Barnard also published the wonderful book 'A Photographic Atlas of Selected Regions of the Milky Way' in 1927 with pictures of many of the dark nebulae that he discovered.
Camera/Film:
Pentax MX SLR w/100mm lens piggybacked on C-14
w/ Kodak Gold 400, Exposure tracked/guided about 15 minutes.
Developed/scanned by:
The PhotoShop, College Ave. Ft. Collins, pushed 1 stop.
Post Development Processing:
In Photoshop 7:
Topaz DeNoise 7 - Moderate Makes stars more discrete
HLVG- Medium -removes green
Adjusted Levels ~15% or so to remove 'cloudiness/haze', improve contrast.
In Thumbs+ 7
Sharpen even less algorithm -Rounds stars a bit and reduces chromatic aberration
Total time to clean up image > 5minutes.
