house system is the best to use?
House systems are a matter of the personal taste of the
Astrologer. We cannot give advice on this choice. There
is no right or wrong. It's more a matter of experience with
I generate a horoscope using the sidereal zodiac?
Yes, you can. Please, choose the zodiac in the respective
drop-down menu in the Extended Chart Selection. We have
three types of sidereal zodiac: Fagan/Bradley and Hindu/Lahiri
(both geocentric), and heliocentric.
you add a new chart technique to the extended chart selection?
No, we do not tend to add new, specialised techniques. Astrodienst's
free online service is targeted at a wide audience of lay persons
interested in astrology, and at the basic needs of serious astrology
students. The purpose of Astrodienst's web services is not to fulfill
the needs of technically oriented specialists who are interested
in very rare astrological methods.
The selection of various chart types available at Astrodienst reflect
those astrological techniques which have been in use in German-speaking
countries during and after 1980, and they reflect Dr. Treindl's
own interest in astrological studies. He programmed the types of
charts which the customers of Astrodienst's chart services requested
and paid for in the 1980ies (before good astrological PC software
existed), and in addition those techniques which either interested
him personally, or some of his close astrological friends.
We are aware that there exist many other techniques which we do
not offer. Among these are 'precession corrected' (should be called
precession falsified) calculations, and converse progressions, which
are not in use in central Europe. Astrodienst is not expanding its
spread of technical charts at this time - we are concentrating on
other services right now.
Please do not be disappointed when the general answer to such requests
is a simple 'no'. Sometimes there are some hidden treasures in our
rich treasure chest, which can be of use. Just take a stroll around.
There are also excellent software programs on the market which fulfill
most of the technical needs an experienced astrologer may have,
for example Kepler by Cosmic Patterns, and Solar Fire. We highly
recommend that experienced astrologers acquire such software for
their own PC. Macintosh users might want to consult the page of
for free astrological software.
you offer converse progression charts?
For 'converse' secondary progressions, use negative age with offset
from your birth date. In extended chart selection, select 'progressed
chart' and, if you are, for example, born in 1950 and want converse
progressions for 2002, the age is 52. Using negative age, you ought
to enter the year 1898 as 'start date'
Primary directions are easily found here:
Free Horoscopes -> extended chart selection -> group Astrodienst
special -> chart type: 3-dimensional chart with primary directions
for 30 years -> additional data tables
This includes converse primary directions by default. Below the
chart drawing, there is a link for 'special options' for various
primary keys and other features.
you offer precession correction in transits or solar return charts?
No we don't. Because we do not consider the method logical and consistent
Tropical astrology uses a frame of reference which moves with the
rhythm of the Sun-Moon-Earth system. The technique of "precession
correction" breaks this system trying to introduce a notion
of "natal birth marks in absolute space". This is false
on several levels:
The reference frame it introduces is not absolute, it translates
and rotates with the (fast) movement of the solar system within
the galaxis. A transiting planet does never return to the point
in absolute space where it once was.
The concept of "return charts" and of transits altogether
is - on a deeper level - a symbolic concept rather than a physical
concept. It should therefore be applied in a consistent symbolic
system and not in an inconsistent potpourri of systems.
If you want to get around precession, we recommend to do "sidereal"
astrology with one of its unprecessed reference frames. We don't
think it makes sense to mix incompatible systems.
Where do I find Antiscia?
For example, in the additional data tables for chart drawing styles 'Munich Rhythms' or 'Studer'.
