We are very pleased and proud to present the November 2013 CCD Imaging Semi-Finalists in the Cloudy Nights Imaging/Sketching Contest.
Because of bad weather I started to looking at old data again. I was not so happy with the old HaRGB version of this data so I did a complete reprocessing.
Barnard 344 is a dark nebula in the constellation of Cygnus. It’s located close to the star Sadr in the Gamma Cygni Nebula (RA: 20h18m57.4s DEC: +40º 40' 01"). Barnard 344 is located on the bottom of the image.
This region is very rich of dark and emission nebulae. On the image also VanDenBergh 130, a reflection nebula in this region, can be seen. It’s the circular cloudshape on the left center of the image. LBN234 is an emission nebula glowing with hydrogen and sulphur in the center of the image.
Barnard 344 was described by Barnard himself as: “Dusky spot, 7' long; like an arrowhead, pointed SW; small star at NE end”.
This image is a combination of narrowband imagery with RGB images taken during a number of nights in July 2013.
