In radio astronomy, mosaicing is the practice of combining multiple pointings of a telescope to produce an image significantly larger than the telescope's primary beam. We consider an approach to imaging and deconvolving interferometric mosaic observations. This approach directly deconvolves a linear mosaic of dirty images. We consider the advantages and limitations of this technique. Projection issues for mosaicing are also discussed. We present an example from a 320-pointing, spectral-line, mosaiced observation of the Small Magellanic Cloud.
