The Spitzer/MIPS 24 and 70 μm imaging of an 11.5 square degree region near the South Ecliptic Pole (SEP) has been carried out in order to complement sub-millimeter wavelength observations (250-500 μm) of the same region of sky taken with the Balloon-borne Large Aperture Sub-millimeter Telescope (BLAST), with the goal of better characterizing the nature of sub-millimeter selected galaxies and their role in galaxy evolution. This field has also been extensively mapped at other wavelengths, and will be imaged from 100-500 μm as part of the Herschel Multi-tiered Extragalactic Survey (HerMES). Candidate extended sources were identified by comparing PRF-fitted fluxes to aperture fluxes at 7.4" and 16" radius (24 and 70 microns, respectively). Sources for which the fluxes disagree (3 sigma) and the corrected aperture flux is higher are considered possible extended sources. These candidates are matched to known objects in NED. Sources requiring an aperture larger than 15" (24 microns) or 36" (70 microns) are measured using aperture photometry on the point source subtracted residual image.
