VdB 14 (right) and VdB 15 (left) are reflection nebulae, a small part of a large dust cloud in Camelopardalis. 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.
