On this page you will find links to scans made of all 32 plates from the Revised MK Atlas. Below you will find links to all of the files available. By clicking on the plate title or thumbnail you will be taken to a plate's individual page.

Individual pages show a 72dpi image of the full plate. In addition, a 150dpi version of the full image is available from the link below the main image. Image files can be large and so the file size is indicated.

If you are looking for a specific star then consult the Star Index which lists all the plates on which a particular star appears. All star names are written as in the Atlas, but with Greek letters transliterated. This index can be cross–referenced with that found at the back of the Atlas Booklet.
