Those interested in this atlas might also be interested in the Firmamentum Sobiescianum of Johann Hevelius of 1690. It's the earliest example of this kind of work (called uranographies), and it's also at USNO. some more examples of Hevelius can be found at Hubble.
Hevelius's drawings are also available in Stellarium , a modern planetarium program.
See also John Bode's Uranographia of 1801, the artwork of which has become the archetype for celestial drawing. Bode also did a version of the Flamsteed atlas.
