 This
            field is dominated by the large face on spiral M61, riding high
            on May evenings within the confines of the Realm of the Galaxies
            in Virgo. At a bright 10.2 magnitude, the inclination is close
            to 1 degree, or nearly face on. It is also quite large at 7 arcminutes,
            and shows intricate details in the arms and core, and is designated
            as a SAB(rs)bc spiral. A very interesting small 13.4 SAB spiral
            lies to its upper left - NGC4303A, only 1.5 arcminutes in size.
            It has bluish arms and some knots in this image. To the upper
            right is NGC4292, a 12.2 magnitude (R)SBr barred spiral, quite
            a bit more yellow in color. It's 1.7 arcminutes long and has
            a B-V index of .9, compared to M61's .5 and NGC4303A which is
            .41. It is by far the yellowest of the group.
