Both Book I and Book II of the Atlas were digitized in their entirety. The 50 photographs, their accompanying page of descriptive text, table of data and identification chart are included with each photograph. In addition, a new image was created by combining the photograph and its identification chart. Where appropriate texts were transcribed and the scans of those pages were not included in the website.

Image Creation

Each page of Book I and Book II was scanned front and back, skipping blank pages, at 600 dpi, with the large format Eyelike® Digital Camera System driven by Eyelike v 3.22. The 600 dpi scans were saved in Adobe Photoshop 6.0 as unaltered tiffs. All images files were inspected, checking filename, orientation, skew, cropping, and file size. The unaltered tiffs were copied onto Mitsui Gold 650 MB CDs. The tiffs were resized to 200 dpi and saved as jpegs. Photoshop was used to batch process the tiff files creating the derivative jpegs.

Website Design

The website was created with Dreamweaver and MySQL. Layout and functionality were designed based on several conversations with Dr. Sowell regarding current study in the field of astronomy, what research tools are most beneficial, and how astronomical data are searched.
