The distance to Hydra and Centaurus from surface brightness fluctuations: Consequences for the Great Attractor model. We present I-band Surface Brightness Fluctuation (SBF) measurements for16 early-type galaxies (3 giants, 13 dwarfs) in the central region ofthe Hydra cluster, based on deep photometric data in 7 fields obtainedwith VLT FORS1.
