Octans dust and molecular cloud

Octans dust and molecular cloud

Octans is an inconspicuous constellation introduced by Nicolas Louis de Lacaille. Its name is Latin for the eighth part of a circle, but it is named after the octant, a navigational instrument. Octans is notable as the location of the south celestial pole but, unlike the north pole, it has no bright pole star. This constellation is circumpolar to the south celestial pole, so it can be seen in Southern Hemisphere skies during the evening in any month of the year.

Octans does not contain many deep sky objects but contain a vast complex of dust and molecular clouds, of which a small part is imaged here. The blue reflection nebula close to the center of the image is cataloged as GN 19.41.5 and is merely 4' across.
