'B 147' is centered in this image. Other dark lanes in this area are LDN 852 and LDN 856 ... This area may be collectively known as the "Fish on the Platter", a large (360') area also known in one of my software packages as B 144 and LDN 857, with a classification of 1 Ir. See Michael Stecker's image of the "Fish on the Platter". This field was re-shot for better stellar images ... see 2007 image here. See the 14.5" version.

The CDS places "B 147" at 20h 06m 59s, +35d 12m 33s, about at the lower middle center of my image.
