Open Cluster Messier 46

This image of Messier 46 has also been taken at the Tacande Observatory in El Paso on La Palma. In fact this is a quite rare object in the sense that it is a star cluster with a planetary nebula. The nebula somehow looks like an eye in the nowhere of space. The image shown above is just an excerpt of the full frame. It is only one 4 minute shot with a modified EOS6D camera with ISO 800. The image is also available in full resolution here.
