This image captures a fascinating series of objects located in the constellation of Cygnus. The objects include many small but beautiful reflection nebulae, emission nebulae, dark nebulae, and star clusters. The entire view spans nearly 50 light-years.

Three bright blue reflection nebulea are the featured objects in the center of this image. NGC 6914, the object namesake, is the most prominent of the reflection nebulae. Located 6000 light years away, it is seen just left of image center. I really like the extent to which this blue nebula is swirled with dark dust lanes. Just right of this nebula, at image center, is van den Bergh 132 (vdB 132). Further to the right is vdB 131, whose blue nebulosity surrounds the open star cluster Dolidze 8.

Most interesting to me are the 4 whitish-yellow ghost-like apparations which appear in the image. The most studied of these 4 has been designated Parsamian 22. The Armenian astrophysicist Dr. Elma Parsamian published a list of 106 star-forming cometary nebulae in 1979, and this object is one of them. It is the comma shaped arc which lies within vdB 131, just right of image center. 3 other much smaller objects also seem to be cometary nebula to me. One is immediately above Parsamian 22, one is just left of vdB 131, and the third is above and slightly right of vdB 131. This object is a variable star and has the designation V1515 Cyg.

The dark nebulae in the image are LDN 899 to the left and LDN 897 to the right. The emission nebulae in the image are LBN 281 to the lower left and LBN 273 to the lower right. Finally, located in the bottom right corner of the image, is the bright open star cluster Dolidze 9.

I really like this part of the sky, with so many colorful and interesting objects.
