The redshift-luminosity distributions for well-defined galaxies and quasars\nin the Sloan Digital Sky Survey (SDSS) are compared for the two\nredshift-distance relations of a Hubble redshift and a de Sitter redshift.\nAssuming a Hubble redshift, SDSS data can be interpreted as luminosity\nevolution following the Big Bang. In contrast, given a de Sitter redshift, the\nintrinsic brightness of objects at all redshifts is roughly the same. In a de\nSitter universe, 95 per cent of SDSS galaxies and quasars fall into a magnitude\nrange of only 2.8, and 99.7 per cent are within 5.4 mag. The comparable Hubble\nluminosity ranges are much larger: 95 per cent within 6.9, and 99.7 per cent\nwithin 11.5 mag. De Sitter space is now widely discussed, but the de Sitter\nredshift is hardly mentioned.\n
