Based on image-tube dissector scans performed at resolutions of 4 A and about 10 A, the 17.3-mag neutral stellar object identified with the radio source PKS 2126-15 is found to have an emission-line redshift of 3.270 + or - 0.004 as well as a very rich absorption spectrum shortward of Ly-alpha. Observed emission features are identified. C IV/Ly-alpha absorption systems are observed at redshifts of 2.768, 2.635, and 2.392. It is noted that PKS 2126-15 is the brightest and one of the intrinsically most luminous QSOs known.
