APM 明亮星系目录列出了南部天空 4,180 平方度区域内 14,681 个亮度高于 $b_J$ 视星等 16.44 的星系的位置、星等、形状和形态类型。使用英国剑桥的自动摄影测量 (APM) 设施，从英国施密特望远镜 (UKST) IIIaJ 天空巡天的玻璃复制板上定位了星系和恒星图像。大多数恒星图像因其图像表面亮度分布的规律性而被拒绝。剩余的图像通过肉眼检查调查材料的胶片副本，并分类为恒星、多恒星、星系、合并或噪声。星系进一步分为椭圆星系、透镜星系、螺旋星系、不规则星系或不确定星系。通过比较相邻板块之间重叠区域的星系星等，将 180 个观测场置于统一的光度系统中。零星等、光度均匀性和照相饱和度均通过 CCD 光度测定进行检查。最后，通过各种内部测试并与几个独立构建的星系目录进行比较，评估了目录的完整性和可靠性。
The APM Bright Galaxy Catalogue lists positions, magnitudes, shapes and morphological types for 14,681 galaxies brighter than $b_J$ magnitude 16.44 over a 4,180 square degree area of the southern sky. Galaxy and stellar images have been located from glass copy plates of the United Kingdom Schmidt Telescope (UKST) IIIaJ sky survey using the Automated Photographic Measuring (APM) facility in Cambridge, England. The majority of stellar images are rejected by the regularity of their image surface brightness profiles. Remaining images are inspected by eye on film copies of the survey material and classed as stellar, multiple stellar, galaxy, merger or noise. Galaxies are further classified as elliptical, lenticular, spiral, irregular or uncertain. The 180 survey fields are put onto a uniform photometric system by comparing the magnitudes of galaxies in the overlap regions between neighbouring plates. The magnitude zero-point, photometric uniformity and photographic saturation are checked with CCD photometry. Finally, the completeness and reliability of the catalogue is assessed using various internal tests and by comparing with several independently constructed galaxy catalogues.
