Description

Sh2-9 and M4

Sh2-9 is a beautiful emission nebula adjacent to M4, an equally beautiful globular cluster. Both in the constellation of Scorpius. Along with the Halpha emission there is an embedded reflection nebula in Sh2-9. This reflection nebula is not visible in this narrowband Ha, around the star near the center of Sh2-9. I plan on completing this project this month, weather permitting, and will post thecolor version.
