The stellar stream in the halo of nearby dwarf starburst galaxy NGC 4449 as seen by the 8.2 meter Subaru telescope and Suprime-Cam
(NAOJ). The larger instrument easily resolves galaxy's halo into its separate constituents and and reveals the stellar steam to be a river of individual stars.
Synthetic luminance was produced by combining separate 255 second G, I, R and OIII filtered exposures. Subaru Suprime Cam exposures collected by Aaron Romanowsky
(UCSC) and Jacob Arnold
(UCSC). Color for this image was produced with a RCOS half meter telescope,
Apogee Alta U16M camera and
Astrodon E-Series filters. Exposure times: 240 minutes Red, 240 minutes Green, 240 minutes Blue (All 1X1). Subaru observations were obtained on January 5, 2011. All image processing by R. Jay GaBany.
