In the constellation of Vulpecula you can find this pretty object,consisting of the Reflection Nebula NGC6820 and the embedded Open Cluster NGC6823 to its right.
At a real distance of about 6000 light-years it apears as an object of 40 arc-minutes dimension.
Very prominent in NGC6820 is the dust-pillar,resembling an elephant´s trunk.This structure is formed by the strong radiation of the nearby stars,which blow away gaseous material,resulting in the trunk-like feature.
The most famous trunk in the heaven can be found inside the nebula M16,also called the Eagle-Nebula.
NGC6823 contains many young,blue coloured stars,aged about 2mio years.
