Description

Prawn Nebula, also known as IC 4628, is an emission nebula located in the Sagittarius Arm of the Milky Way, around 6,000 light-years from Earth in the constellation Scorpius. It forms part of the tail of the "False Comet" anchored by the bright open cluster NGC 6231. (Wikipedia)

This image was made using only the information captured using a H-Alpha filter. It allows to see the detail inside the nebula, mainly some gas globules that probably will be the birthplace to new stars.
