We present the first results from a wide solid angle, moderately deep Chandra survey of the Lockman Hole North-West region. Our nine ACIS-I fields cover an effective solid angle of 0.4 deg² and reach a depth of 3x10^–16 ergs.cm^–2.s^–1 in the 0.4-2 keV band and 3x10^–15 ergs.cm^–2.s^–1 in the 2-8 keV band. The best-fit log N-log S for the entire field matches well onto that of the Chandra Deep Field-North. We show that the full range of the ``cosmic variance'' previously seen in different Chandra fields is reproduced in this small region of the sky. A counts-in-cells analysis shows that the hard-band sources are more strongly correlated than the soft-band sources.
