This picture shows you three Messier's galaxies of M95 (right), M96 (left), and M105 (upper left) positioned between forelegs and hind legs of Leo. M95 is a spiral galaxy with a visual diameter of 5 arc minutes, arms are coiled up around the nucleus. M96 is also a spiral with almost same size as M95, you can detect two undeveloped arms stretching in east-west direction. Both galaxies are lying about 33 millions light years away, forming a small-scaled galactic cluster with neighbored dimmed galaxies.
M105 is an elliptical galaxy around the center of Leo. The galaxy is lying about a degree north of M96, one of principal members of a small galactic cluster formed by some dimmed galaxies around this field. M105 lies at right of three triangled galaxies in a magnified image, and other two ones are named NGC3384 (upper) and NGC3389 (left), respectively. M105 has a diameter of about 5 arc minutes and visual magnitude of 10. It's a round shaped elliptical so you cannot resolve clear structures.
