44 Cygni


44 Cygni is a supergiant star in the constellation Cygnus. It is surrounded by the reflection nebula vdB 133. The nebula Sh 2-106 is found less than a degree to the northwest.
44 Cygni is the primary component of the double star AC 18. Its companion, AC 18 B, has a magnitude of 9.59 compared with 44 Cygni's magnitude of 6.2. They are visually separated by 2", making it challenging, but not impossible, to view optically.

vdB 133

vdB 133 is the reflection nebula surrounding 44 Cygni. It is notable for being a much more white color than the blue of most reflection nebulae. The nebula has an apparent size of 12'. It is possible the reflection nebula is located on the far side of 44 Cygni as viewed from Earth, since the white light seen from the star differs from the more blue color expected from the scattering of light through a nebula.
