For this reason is also named Bode Nebula. 26'x14' in dimensions, is oval with a bright center. M82 (NGC3034), visible at upper left and with dimensions of 11'x4.5', is irregularly shaped. It shows a radial expansion from the center at a speed of 2000 km/sec. The other two galaxies well showed in the picture are NGC3077 (lower left) and NGC2976 (lower right). Other faint galaxies can be noticed in the field. The close-up below shows them very enlarged.
