Abstract
We are developing an automatic star-counting method that will quickly and reliably recognize both bright and faint stars, and that will do so in fields complicated by the presence of irregular, diffuse optical emission. To guide construction of the stellar image recognition algorithm, and to check the method for reliability, we have manually counted stars in a 2 X 2 degree test field. Here we discuss novel aspects of our counting method and consider two applications of the map of blue extinction produced from our star counting of the region around NGC 281: (1) we use the ratio of infrared intensity at 100µm to extinction as a probe of dust temperature; and (2) we examine the correlation of extinction to CO spectral line intensity.
