The Magellanic Cloud Emission-Line Survey (MCELS) obtained observations toward the Large and Small Magellanic Clouds (LMC and SMC, respectively) over six years using the UM/CTIO Curtis Schmidt 0.61m telescope to produce deep images in [O III], H-alpha, and [S II] emission-lines, in addition to adjacent green and red continuum filters. This survey covered the central 8 degrees x8 degrees of the LMC and the central 3.5 degrees x4.5 degrees of the SMC and encompasses most of the gaseous extent of each galaxy with an angular resolution of 5 arcsec or better, allowing us to identify and study interstellar structures on similar to 1-1000 pc physical scales. We have modified the SuperMACHO/Essence-w pipeline, developed for Blanco 4m Mosaic II data, to reduce MCELS data in a uniform manner. In addition to basic reductions (e.g., bias subtraction, flat-fielding, etc), this pipeline uses spatially-varying convolution kernels to match the PSFs of the narrow-band and broad-band images and produce continuum subtracted images for the narrow-band filters. We use flux measurements of previously identified planetary nebulae (PNe) in the LMC, e.g. Reid & Parker (2010), and photometry obtained by our pipeline to create color-magnitude and color-color diagrams in the MCELS filters to search for new PNe candidates in the LMC.
