What it is and why it matters

The midpoint is the middle point between two positions. The panel looks for planets near such points, and also separately shows mirror positions — antiscia — and links for declination.

When to use it

  • for planetary midpoint research.
  • When you want to compare aspects for longitude with relationships for declination.
Terms explained
Midpoint
The middle point between two positions on the zodiacal circle, also called their half-sum. The opposite point may also be considered.
Harmonic
A transformation that multiplies longitudes by a chosen number and reduces them to the circle. It helps examine particular angular relationships together.
Declination
The angular position north or south of the celestial equator. It is used for parallels and contra-parallels, separately from aspects in zodiacal longitude.

Where to find it

The right panel is “midpoint”.

How to use it

  1. Select the “Planets”, “Tree” or “All” mode to view the midpoint.
  2. Set the harmonic and orb; if necessary, turn on the opposite points (+180°).
  3. Go to antiscia and select the reflection axis. In parallel mode, see parallels and contra-parallel for declination.

Settings and options

Select an option to learn how it works and when to use it. The label beside its name shows whether it affects calculations, chart appearance or data.

Planets / Tree / All / Antiscia / ParallelsAppearance

Modes of different relationships: planets at the midpoint; tree around a point; complete list of midpoints; reflection from the axis; contacts behind declination.

What changes
Type of Table. Antiscia and parallels explore different geometric relationships than ordinary midpoints.
When to use it
Start with “Planets” to see only contacts; “All” is needed to view the most calculated midpoint.

HarmonicCalculation

Longitude Multiplier for the analysis of repeated angle ratios.

What changes
The full, fractional and negative values are allowed. The note shows an effective orb after considering the harmony.
When to use it
To play the method, write the harmonic and orb together; a large multiplier does not mean “precise analysis.”

OrbCalculation

Admission to display the contact point with midpoint, antiscia or current mode parallel.

What changes
A narrower admission gives less results; in harmony read the reckoning in the note.
When to use it
For an accurate study, start with a small admission; an empty table can be a correct result.

Include opposite points (+180°)Calculation

Includes the point opposite to the main midpoint on the circle.

What changes
On: the midpoint axis is explored; off: only the main point.
When to use it
Enable for the midpoint axis technique; the "opposite" tag explains the origin of the additional contact.

Axis: Cancer — Capricorn / Asc — Dsc / MC — ICCalculation

The mirror reflection axis in antiscia mode.

What changes
Cancer — Capricorn gives a standard reflection from the sunrise axis; other variants use the angles of the current chart.
When to use it
Asc-Dsc and MC-IC require a reliable birth time. Call it in the conclusion.

The result

The list will show bets and points within the chosen orb.

Worked example

This is a teaching example; results for your chart may differ.

Situation
You are checking for a third planet in the middle of Sun-Moon.
What to do
Select the planets mode in midpoint and small orb.
How to read the result
The found line shows a geometric coincidence according to the current rules; first check whether the opposite point is taken into account.

For professional practice

The tree, full list, antiscia and parallel modes provide several ways to verify one hypothesis without mixing coordinates.

What to check for a precise comparison

Fix the harmonic, actual orb and antiscia axis; parallels and contra-parallels are checked for declination.

Keep in mind

In harmony, longitude is multiplied by its value; the applied orb is shown in the note. Parallels are calculated between bodies, without angles.
