The large Eliptical IC 1459 near the centre is the largest and brightest galaxy at 4.9' X 3.5' and
mag 10.5 while the beautiful open spiral galaxy IC 7418 lower left is the largest spiral at
3.75' X 2.5'and mag 11.5. There are also a number of faint and diffuse elliptical/irregular galaxies
in the field.
