Astrological feature list

1) For beginners:

  • Tooltip help for every chart feature
  • Interactive astrological interpretation of objects on the chart (planets, houses, Zodiac signs, etc)
  • Extended computer-generated interpretations of natal (birth) and transit (astrological forecast) charts
  • HTML-based help system
  • Open library of interpretation texts, with a convenient system for cataloging texts, and the ability to select texts for a particular type of chart
  • Sabian symbols
  • Recall previously created charts instantly from the History log
  • Forecast up to 10 years ahead using a transit comparison with the natal chart, presented in graphical form
  • Facilities for an interactive space photo-album and mythological art gallery
  • I-Ching Oracle with multimedia facilities
  • Insonation of interpretation texts by speech synthesizer

2) For the professional astrologer:

  • Radix charts; single and dual charts (transits, synastry, various kinds of directions and progressions: solar, lunar, embolismic lunation, phase progressed, profected, ...); any scale of progression and direction (including converse); Primary Directions (with real movement of planets); Primary Directions using an oblique ascension at calculation direction angle between promissor and signifocator, are considered correct traditional method; Davison relationship chart; composite chart; coalescent chart; harmonic charts; Uranian 90 degree dial charts; Traditional Charts: some kinds of traditional (square) cards in the European medieval style and in several Indian styles.
  • Complex charts: up to 7 planet rings in one chart wheel
  • Fixed charts: any previously-calculated chart can be included in a complex chart
  • Multibot charts allowing to create several data sets in one chart (the data set is pair "initial, background"). Thus there is a possibility to place on a chart simultaneously a several natals and a several adhered to everyone natal derivative charts. In particular, it is possible, for example, to look aspects of planets of a progression of one natal to planets of another natal, aspects of a progression of several events to one natal, etc. [more]
  • Option of topocentric, geocentric, heliocentric, horizontal and other systems of coordinates; several kinds of sidereal ajanamsa
  • Right (3-dimension) displaying of Placidus house cusps at natal chart, at celestial sphere, at geographical map (ACG)
  • Interactive adjustment of chart properties (colors, dimensions, objects displayed, etc); control of various operating parameters
  • Astrological tables: Lunar days (and Moon Rises and Sets, New moons, Full moons), Sunrises and Sunsets, Planetary Hours, Ingresses of the Moon and planets, perigee and apogee of the Moon
  • Parallels, contraparallels, antiscia, and contrantiscia
  • Interactive dynamics of time. Examine, for example, change of birth time resulting from the synchronous change of a progression chart
  • Acceptance of centi-seconds of time and geographical coordinates
  • Horary Wizard, allowing to automate some stages of construction and the analysis horary charts: a choice of significators and derivative houses, definition of conditions of realisation of aspects etc.
  • 'Pick and turn' technology for interactive chart adjustment using the chart wheel's planet glyphs, with immediate recalculation of planet positions and aspects
  • Parameters of planetary orbits and elements of rotation displayable on the chart
  • Utilize asteroids, stars, nebulae, eclipses
  • Support for hypothetical planets of the Uranian school and others; it's even possible to define your own planets
  • Arabic parts (Pars), user-definable
  • 27 systems of houses Krusinski house system
  • Interactive dynamics of geographical location. Examine, for example, places for relocation
  • Graphic diagrams of planet movement and aspects formed: select radix, transit, progression, or directions for any period of time from 3 days to 120 years, using any subset of planets and houses, in harmonics of 360, 90, 60, 45, 30 degrees
  • Run second ZET instance with a chart, selected from Data Base or History log
  • Database facilities with embedded photos
  • High-quality output to laser and inkjet printers using TrueType fonts
  • and more features are added regularly
