Notes: |
M105 is a member of the Leo I group of galaxies. It is a typical representive of elliptical galaxies. Because of it's uniformity of color over the entire range of luminosity, M105 is used as a photometric standard for the surface brightness distribution of elliptical galaxies. The other two bright galaxies in the above image are NGC3384 and NGC3389. Many background galaxies, which can be found in the image are members of the more distant galaxy cluster ZwCl 1045.8+1251. |
