We present a new method for interferometric imaging that is ideal for thelarge fields of view and compact arrays common in 21 cm cosmology. We firstdemonstrate the method with simulations for two very different low frequencyinterferometers, the Murchison Widefield Array (MWA) and the MIT Epoch ofReionization (MITEoR) Experiment. We then apply the method to the MITEoR dataset collected in July 2013 to obtain the first northern sky map from 128 MHz to175 MHz at about 2 degree resolution, and find an overall spectral index of-2.73+/-0.11. The success of this imaging method bodes well for upcomingcompact redundant low-frequency arrays such as HERA. Both the MITEoRinterferometric data and the 150 MHz sky map are publicly available athttp://space.mit.edu/home/tegmark/omniscope.html.
