Signatures: [A]�p2�s Contains celestial cartography in the form of mainly regional stars-only plate maps of areas of the sky, showing both the northern and southern hemispheres from the internal perspective, using mainly the equatorial coordinate system, as follows: 1. Northern Hemisphere centered on the equatorial pole but using an ecliptic-pole-based map grid; 2a and b: Area surrounding the ecliptic and equatorial poles; 3a and b: Area around Andromeda/Perseus; 4a and b: Area around Auriga; 5a and b: Area around Leo Minor and Lynx; 6a and b: Area around Ursa Major; 7a and b: Area around Bootes; 8a and b: Area around Hercules and Corona Borealis; 9a and b: Area around Ophiuchus; 10a and b: Area around Aquila; 11a and b: Area around Cygnus; 12a and b: Area around Pegasus, Delphinus; 13a and b: Area around Aries; 14a and b: Area around Taurus, Orion; 15a and b: Area around Gemini (with both obsolete Herschel telescope constellations); 16a and b: Area around Cancer; 17a and b: Area around Leo, Sextans; 18a and b: Area around Virgo with obsolete constellation Berg Maenalus (Mons Maenalus); 19a and b: Area around Scorpius and Libra; 20a and b: Area around Sagittarius, Scutum; 21a and b: Area around Aquarius and Capricornus; 22a and b: Area around Pisces; 23a and b: Area around Cetus; 24a and b: Area around Orion, Eridanus, with great central prominent placement of the obsolete German heritage constellation Sceptrum Brandenburgicum; 25a and b: Area around Monoceros, Canis Major and Minor; 26a and b: Area around Hydra, Sextans, Crater; 27a and b: Area around Virgo, Corvus; 28: Pair to the Northern Hemisphere map centered on the equatorial pole but rendered with an ecliptic-based grid; 29. Map showing the new Southern constellations of Lacaille - circumpolar area south of the Tropic of Capricorn.
