Upper panel: g-band image of the 4 × 1 deg² (corresponding to 1.1 × 0.3 Mpc²) strip of the core of the cluster north of M87. The lower panels are a magnified view of the boxed regions marked on the upper panel. They show the pseudo-colour images of NGC 4569 and IC 3583 (lower-left panel) and of the NGC 4438-N4388-M86 complex (lower-right panel) obtained combining the NGVS optical u and g in the blue channel, the r and NB in the green, and the i and the continuum-subtracted Hα in the red.
