We have used the Big Throughput Camera at CTIO to image around the Hubble Deep Field--South in a narrow--band filter centered on Ly-alpha at the redshift of QSO J2233-606 (z=3D2.25). A total 4 hours of exposure reaches limits of 8.0*E(-17) ergs cm(-2) s(-1) (5sigma for point sources with 1.5arcsec seeing). The images cover 40\arcminx40' and sample a cube 60 co-moving Mpc on a side at the redshift of the QSO (for H_0 =3D 50 km/s/Mpc and q_0 =3D = 0.5). Broad-band, uB, images were also obtained to measure the continuum. We discuss emission-line objects associated with the QSO. These objects may outline a large-scale structure at z=3D2.25.
