Position Angle: minus 89 degrees (Pinpoint)
Description:
This beautiful pair of reflection nebulae are a small part of a large
dust cloud in Camelopardalis. They contain both reflection (blue)
and emission (red) components, although the emission component is
subtle and can be seen as the peripheral pale red regions in the above
LRGB image. VDB 15 is the large nebula on the left, surrounding
the magnitude 5 central star C Cam, while VDB14 is the sickle-shaped
nebula on the right, next to the magnitude 4 star B Cam (to its lower
right). What makes this image one of my favorites is the
widefield views, available in the links above. The abundant,
colorful stars in this field are very dramatic, and there is an
occasional hint of blue nebulosity surrounding some of them (see the
star in the lower right on the widefield views). In addition, the
widefield view makes it easy to appreciate an obvious drop off in star
density on the left hand side of the image (due to intervening dust).
