Recent studies have found the earth's peculiar velocity to be significant inmicrowave background based tests for compact cosmic topology, and modificationsto these tests have been proposed. Tests of non-gaussianity, weak lensinganalysis and new tests using improved CMB data will also be sensitive topeculiar velocity. We propose here to simplify matters by showing how toconstruct a deaberrated CMB map to which any test requiring a Hubble flowviewpoint can be applied without further complication. In a similar mannerdeaberration can also be applied to object surveys used for example intopological searches and matter distribution analysis. In particular we haveproduced a revised list of objects with z > 1.0 using the NASA/IPACExtragalactic Database.Comment: 8 pages, 1 figure, v4 accepted by Ap
