NGC4490

ngc4490v4

NGC4490, sometimes called the Cocoon Galaxy, is seen here with its small companion, NGC 4485. The two galaxies have passed each other by, and if you click on the image to get the larger view you can see stars and galactic material being sucked out of each galaxy due to gravitational tidal forces. These galaxies are about 50 million light years away. The distance between them is about 24,000 light years. This image is a total of 6 hours and was taken on March 11 and 12, 2012 with my Hyperion Astrograph under the automated control of CCDAutopilot.
