Galaxy M 82

First astrophotographic project done in collaboration with another astrophotographer: Filippo Scopelliti.Filippo captured the luminance, while I used chrominance, hydrogen jets and I worked out the union of our two images.

The galaxy Cigar (or M 82) is a starburst galaxy located in Ursa Major, 12 million light years from us.

The "nearby" galaxy M 81 interacts with M 82 and causes hydrogen jets to escape from the central part.
