Luminosity profiles for six Local Group galaxies are derived based on observations made with a CCD camera and a set of five telescopes. The telescopes range in size from a 105 mm focal-length lens to the MMT, providing fields ranging from 3arcmin to 5°. This instrumentation permits uniform, calibrated photometry to be obtained over a wide range in angular scale with much greater ease than has been possible previously. The galaxies observed were M31, M32, M33, NGC 147, NGC 185, and NGC 205. Total magnitudes are derived for all galaxies except M33, and nuclear magnitudes are derived for the three galaxies that have distinct nuclear components. Mass/light ratios are computed for the bulge in M31 and M32.
