Description

M109 is a barred spiral galaxy found approximately 60 million light years away in the constellation Ursa Major. Below the center galaxy there are three other smaller galaxies, thought to be satellites to the spiral which has a disk diameter of 120,000 light years making it slightly larger than our Milky Way.

Messier 109 is actually the most distant object of the 110 deep space objects listed in the Messier catalog, a list of objects discovered by French astronomer Charles Messier. The catalog was originally published with only 103 objects. M109 along with 5 other galaxies and a globular cluster were added to make up the final 110 objects between 1921 and 1966 when evidence was discovered that suggested Messier and his assistant Pierre Méchain observed them shortly after his original 103 objects were published in 1781.

This image was taken back in mid March as first light for the Atik 383L. Didnt get around to capturing color data. Because of the way mono CCD cameras work it will take another 3 nights to shoot a good amount of data through red, green and blue filters, which could then be combined with this luminance frame resulting in a full color image.
