does the Astrodienst Composite Chart come out with a different Venus (or Ascendant)
placement to the one I've seen somewhere else?
There are different ways of calculating composite charts. One of
these differences concerns Mercury and Venus: some astrologers transpose
Mercury and Venus by 180° to the opposite sign, if they come out
on "the wrong side of the Sun" in the chart.
We offer both variants. In the chart section of the
AstroShop, for type 62, the two
planets are always put on the side of the Sun, in chart type 671
and all reports they are not moved but remain where they technically
For the calculation of the Ascendant, see question No. 2 below.
Why does the
Ascendant of the composite chart change by 180° if I change the birth
time of one of the partners?
The Ascendant in a composite chart can be computed in different ways, depending
on the technique the astrologer uses.
One cannot look at the Ascendant in an isolated way without considering the
position of the MC. We calculate the MC first and go from there. Sometimes
a raw calculation of the Ascendant results in an impossible sequence of houses.
A change in the birth time of one of the partners may have the same result.
This is why the ASC / DESC axis is swapped (by 180°) in such cases.
With midpoints, there is always an axis with a near and a far midpoint for
each pair of factors. Both midpoints are nearly equivalent in meaning and
can be reversed if needed.
- Is there a way
of setting a composite chart so it can be added to My Astro? I would like
to use it as a 'normal' chart for synastry, astromap etc.?
Unfortunately, there is no such way. A composite chart cannot be used as a 'normal'
chart because it isn't one. It does not represent a real constellation of planets
but is a mere mathematical construction. This precludes its use in many of the
standard astrological techniques.
- Can a composite
chart contradict the synastry chart?
Both views represent quite different perspectives, and of course, they can disagree.
The composite is a third chart, calculated from the two individual horoscopes,
and it shows the dynamic of the relationship as a separate (third) entity. The
synastry compares the two individual charts and points out what the two people
involved "trigger" in each other.
There might be contradictions in relationships, just like individuals are full
of contradictions by nature.
You can find more information on synastry and composite charts in the AstroShop.

- What kind of
chart comparison can I do for twins? A composite chart comes out the same
as the natal charts, are there other methods?
The composite chart does not work for twins. The only approach for a relationship
chart for twins, which we know that works, is the one by our author Mona Riegger,
as used in the report "Horoscope for Two". It can be ordered in the
Mona's approach makes a distinction between 'the older' and 'the younger', which
is always defined with twins, even when born by cesarean section. Then she reverts
some elements of the Davison relationship chart for the younger one, getting
two distinctive charts that way. She is able to make very interesting deductions
about the relationship between the two. Not accidentally, Mona is a mother of
