I found this by accident, and thought it might be of use over on this board. The text is in the National Library of Wales, and it has extremely clear, enlarged images. The whole book has been scanned & put up online. It's the oldest scientific manuscript found on the constellations/astrology/astronomy & myth. Some has been copied from older sources, but all of it is still Medieval or older.

The astronomy book by page is over here -- http://digidol.llgc.org.uk/METS/AST00001/frames?div=37&subdiv=0&locale=en&mode=reference
And this gets you to the thumbnails, you can click through faster than when they're fully sized. Most of the pictures & full sky charts are in the first half of the book.
