As part of a combined Sunyaev-Zeldovich Effect (SZE), X-ray and weak lensing
survey of low redshift (z<0.1) X-ray clusters, we present SZE images of the
z=0.059 X-ray cluster Abell 3266 at three observing frequencies (150, 220, 275
GHz) and after the spectral subtraction of primary Cosmic Microwave Background
(CMB) anisotropies. These images were generated using the ACBAR bolometer array
operated on the Viper telescope at the South Pole. The multi-frequency data
from ACBAR should allow us to overcome one of the main obstacles facing the
analysis of SZE observations of nearby clusters, i.e. contamination from
primary Cosmic Microwave Background (CMB) anisotropies.
