“…Creating universal access to such irreproducible data is therefore a worthy goal, and one which many groups around the world are pursuing. Examples include the Wide-Field Plate Database (WFPDB; Tsvetkov et al 2015), the Astronomical Photographic Data Archive (APDA; Castelaz 2009), and the Archives of Photographic PLates for Astronomical USE (APPLAUSE). 4 Our goal in this work is to create a catalog of stellar magnitude measurements from a 1905 plate from Barnard's Atlas with low-cost, accessible tools and demonstrate its value for photometric variability studies.…”

In the second paper in this series, we improve on our previous demonstration of the ability of a commercially available graphic arts scanner and cost-effective analysis tools to produce scientifically useful scans of astronomical photographic plates. We describe a method using freely available tools to extract magnitude measurements from the star images on sky-survey plates, such as are stored in observatory archives around the world. We detail the use of this method on one plate in particular, Plate 8 in E. E. Barnard’s A Photographic Atlas of Selected Regions of the Milky Way, examine the effects of our scanning method on our magnitude measurements, discuss the difficulties encountered when measuring the magnitudes of stars in crowded fields, and present a case study of red supergiant stars appearing within the field. Our work results in a catalog of more than 66,000 measurements of stellar positions and magnitudes in the central 6.°8 × 6.°8 field of view.
