Andreae is only known to have produced two celestial broadsheets; the present charts. They are centred on the equatorial poles using a polar equidistant projection with geocentric orientation. The maps are influenced by Coronelli and could be bent into cones and viewed from the inside to give an illusion of the celestial vault.
