VdB 130 (right in the middle of the image) is a reflection nebula associated with a young open cluster in the constellation Cygnus. It is located in the central part of the constellation, about 1.5 ° to the southwest of the star Sadr. Clearly associated with the complex of nebulae beyond the Fissure of Swan, its distance was initially estimated at about 1000 parsecs (about 3260 light years) and subsequently recognized more accurate about 1500 parsecs (4890 light years). It appears illuminated directly by the star HD 228789, which is part of a very young star cluster, forming an OB association, linked to reflection nebula. Linked to this structure is also the small H II region DWB34 and a number of infrared radiation sources. Aamong these is IRAS 20153 + 3850, coinciding with the young blue star HBHA 3703-01, spectral class B5V or B6V and magnitude 13.6, surrounded in its turn by a small and dense nebula named GM 2-39. Below is a highly magnified crop of the nebula itself:
