Clouds in the Unicorn
This is a photography of a beautiful sky zone, in the Monoceros constellation (the Unicorn).
It is a zone with very subtle deep sky objects, that in combination show a very attractive portrait.
In the image there are some reflection nebulae: NGC2170, NGC 2182, NGC 2183, NGC 2185, Ced 65, Ced 66, Ced 71, some emission nebulae (such as LBN 999), while the presence of some dark nebulae is appreciated because they are obstructing the vision of far objects.
