A nice Galaxietriplet in Coma Berenices. The maingalaxie in the image is NGC4725, discovered by William Herschel in 1785. This Galaxy is interacting with the companion northeast NGC4712. The Tidalstreams indicates this process and is clearly visible in the image, but better in the inverse version (see: http://www.skypixels.at/ngc4725_info.html). West of NGC 4725 you can see NGC 4747 with a distance of 190 mio LJ.
