14 & 15 - Reflection Nebulae
in Camelopardalis
Contrasty version:
Less contrasty version:
VdB 14 (right) and VdB 15 (left) are reflection nebulae, a small part
of a large dust cloud in Camelopardalis. They can be seen at the bottom
of this very wide field shot from 2010:

VdB 14 is illuminated by the magnitude 4.29 star HD 21291 - variable
blue supergiant of type Alfa Cygni, which also has the name CS
Camelopardalis. Together with the surrounding stars it forms the
central part of an OB association known as Cam OB1, placed at a
distance of about 2600 light years from the Solar System, on the outer
edge of the Orion's Arm. VdB 15 is a large bank of gas illuminated by
the bright star HD 21389, well visible to the naked eye thanks to its
magnitude of 4.55. HD 21389 is also a variable blue supergiant of type
Alfa Cygni, being catalogued also as CE Camelopardalis. The distance to
VdB 15 is also 2600 l.y., which means VdB 14 and VdB 15 are close in
space. In fact, both of them are part of the same molecular cloud.
