The Culture Diff' ArchaeoAstronomy softwares

The Culture Diff' ArchaeoAstronomy softwares

The Culture Diff' ArcheoAstronomy softwares have been developed on the basis of programs conceived during my doctoral thesis devoted to Ancient Egyptian Astronomy. A unique feature of these softwares is that they combine several algorithms of astrometry (relating to the positioning of stars on the celestial vault) and of photometry (linked with the brightness of the object sighted, the luminosity of the sky, local atmospheric conditions and the visual acuity of the observer). As a consequence, they allow to accurately determine the time and place (azimuth and height above the local horizon) at which a celestial object appears/disappears on/from the local celestial vault - at dusk, in dark night or at dawn.

Astronomy softwares

To date, three astronomy softwares are at your disposal, leading you to determine with great accuracy the:

days of heliacal rising and setting
of any star visible with the naked eye


Sirius and Orion in twilight

days of solstices and equinoxes
in any place of terrestrial longitude


Rising of the spring Sun above the Black Mountain

astronomical source of orientation
of any monument erected since 4712 BC


Shooting stars on the castle of Penne


The access, for an indefinite period, to the user interface of these regularly updated softwares, is available for a fee. But free tests of these softwares are at your disposal within the Culture Diff' Client Area.
