There few galaxies in Leo that are as detailed and display outer structure like this one. This 9.7 magnitude object spans a huge 13 arcminutes across, and in the same field we can find many distant 16th magnitude galaxies as well. To the lower right (seen in the larger frames) is the asteroid Fiducia 380, currently at 14.7 magnitude.
