This image shows an area of about 60 x 40 arcmin. in the constellation Cygnus, about 2.5 ° north of the star Sadr (γ Cygni). NGC 6914 is a small system of reflection nebulae stretched in a north-south direction. The different parts of NGC 6914 are catalogued as NGC 6914A (or VDB 132, Bernes 24, DG 163, Ced 176e, Magakian 825), NGC 6914B (VDB 131, DG 162, Bernes 23, Ced 176d, Magakian 821) and NGC 6914C (Bernes 25, Magakian 824). Its association with the great nebulous complex IC 1318 and its tenuous reddish filaments is very evident and the whole complex is at the distance of about 1690 parsec (5500 light years), thus being near the association Cygnus OB2. The nebula reflects the blue light of the star BD + 41 ° 3731, having spectral class B3 and a magnitude 9.84; it has strong emission lines and is classified as a Be star. The image also contains several bright and dark nebulae (see mouseover). Several small objects also can be seen here. Among them are Parsamian 22 - an interesting small bipolar nebula, and a FU Ori variable star V1515 Cyg, which has a clear visible small shell.
