Sh 2-2
HII Region in Scorpius
From Wikipedia, the free encyclopedia
Sh 2-2, also known as Sharpless 2, is an emission nebula in the constellation of Scorpius. It appears as a mid-range brightness making it difficult to view. It is believed to currently host an X-ray binary star that originated and was ejected from the Scorpius OB1 association. Amateur astronomers can usually see it with a wide field telescope and a hydrogen-alpha filter.
