Deep Mosaic of the Fornax cluster core
This is a deep optical mosaic of the Fornax cluster’s core,
covering 1.6 square degrees. The data were acquired with ESO/MPG 2.2m/WFI,
using a transparent filter that nearly equals the no-filter throughput
and thus provides a high signal-to-noise ratio. Based on an approximate
conversion to V-band magnitudes, the unbinned and binned mosaics
(0.24 and 0.71 arcsec/pixel) reach a median depth of 26.6
and 27.8 mag/sq.arcsec, respectively.
