The stellar stream in the halo of nearby dwarf starburst galaxy NGC 4449 was detected in deep integrated-light images from the Black Bird Remote Observatory. Mouse-over the image to view an inset that resolves the stream into its constituent stars.Click the image for a larger view.

This image was produced with a half meter RCOS telescope, Apogee Alta U16M camera and Astrodon E-Series filters. Exposure times were 1,080 minutes Luminance, 240 minutes Red, 240 minutes Green, 240 minutes Blue (All 1X1). Black Bird observations were conducted over a series of nights spanning April 13 through June 10, 2010 and again between January 13 and January 28, 2011
