The Astro module of Optuma includes a fully user-definable natal chart which instantly displays any number of planets, asteroids, node positions, and Natal Houses (eg Ascendant, Midheaven), allowing key planetary relationships to be easily identified. The position of the houses are based on Placidus house system.
Non-standard items, such as minor asteroids, can be imported into the chart.
The chart is broken up into the twelve houses of the zodiac and also takes into account declination, displaying the planetary bodies in their true position according to Longitude and Declination.
The above example shows that on this particular date Mercury is square Uranus (90° apart), the Sun is opposite (180°) Saturn (R = in retrograde) and square to the Ascendant..
To access the Natal chart select it from the Astro folder located under the New menu.
The Natal Chart at a Glance
The Optuma natal chart shows the 360-degree circle with the selected planets / bodies in view inside the ephemeris.
The Structure Panel
When the natal chart is opened a structure panel will appear on the right side of the screen. This is where date and time of the chart can be set, and the planets, astro bodies and aspects to be displayed can be selected.
A new chart will open at the current time and date. To change this, click on the date to open the navigation console:
From here you can move forward and backwards in time, by either pressing the + or ‘-‘ buttons in minute, day, year or century increments. Alternatively, drag the slider to the left or right.
To select a specific date click on the date icon in the bottom-left corner to open a calendar.
To select the objects to be displayed on the ephemeris click on the + and - to expand or hide the group, and tick the required boxes. The bodies available are:
The Mean of 5 is the longitude of Jupiter+Saturn+Uranus+Neptune+Pluto divided by 5.The Circle of 8 is Mercury+Venus+Mars+Jupiter+Saturn+Uranus+Neptune+Pluto divided by 8
The Houses and Angles
The ephemeris is broken up into the twelve houses of the zodiac. The angle of each house is displayed on the outside of the circle, starting from zero degrees Aries.
Located in the middle of each house is its symbol:
House Symbol Ephemeris Angles
Aries ? 0 – 29 degrees
Taurus ? 30 – 59 degrees
Gemini ? 60 – 89 degrees
Cancer ? 90 – 119 degrees
Leo ? 120 – 149 degrees
Virgo ? 150 – 179 degrees
Libra ? 180 – 209 degrees
Scorpio ? 210 – 239 degrees
Sagittarius ? 240 – 269 degrees
Capricorn ? 270 – 299 degrees
Aquarius ? 300 – 329 degrees
Pisces ? 330 – 360 degrees
The selected planets will be displayed inside the ephemeris with the Earth at the centre.
A line joining the ephemeris and the planet will be displayed to indicate whether the planet has a North or South declination to the Sun or Earth. The length of the line will also give an indication as to where a planet’s declination is in relation to other planetary bodies.
Where a planetary body has an (R) next to it, this is an indication that it is in retrograde.
Importing Additional Asteroids
Optuma allows for the manual importing of additional asteroids that aren’t already in Optuma. For more information, click here.
Actions & Properties
Clone Chart: When selected, the existing chart will be duplicated. It will be placed above the existing chart, from here it can either be moved to a new page or tiled alongside your existing chart(s).
Print Chart: Prints the active page, which is opened as a PDF.
Restore Default Settings: Click this action if you have adjusted the default settings of the Ephemeris, and wish to return to the standard properties originally installed with Optuma.
Save Aspects to Clipboard: Copies the raw data values of the selected aspects (planets, dates, aspects, angle) to your clipboard, which can then be used in other programs (such as Notepad, Excel, etc).
Save Planets to Clipboard: Copies the raw data values of the selected planets (name, right ascension, declination) to your clipboard, which can then be used in other programs (such as Notepad, Excel, etc).
Save Settings as Default: If you have adjusted any of the ephemeris settings (selected planets and aspects, for example) you can save the adjustments as your new default setting. Each time you open a new ephemeris it will display using the new settings.
Aspects: The key relationships selected between planets will be highlighted on the ephemeris when they occur. The following aspects are available:
- Conjunction – planets are within zero degrees of each other
- SemiSextile – 30 degrees
- SemiSquare – 45 degrees
- Sextile – 60 degrees
- Quintile – 72 degrees
- Square – 90 degrees
- Trine – 120 degrees
- Sesquiquadrate – 135 degrees
- BiQuintile – 144 degrees
- Quincunx – 150 degrees
- Opposition – 180 degrees
- Parallel – equal declination
- Contra-Parallel – opposite declination
Longitude Orb: Allows you to adjust the tolerance for what constitutes a planetary relationship. For example, if the sextile (60 degrees) aspect is used and the orb is set to 2 then Optuma will consider any planetary relationship between 58 degrees and 62 degrees as having met a sextile relationship.
Latitude Orb: Allows you to adjust the tolerance for the declination (only applicable for the Parallel and Contra-Parallel aspects) For example, if the declination orb is set to 2 then Optuma will consider planets to be parallel if their declinations are within 2 degrees of each other.
Fixed Points: Allows you to add your own point at a fixed angle on the chart, eg 144°.
Show Planet Names: Untick this box to remove the names of the planets from the ephemeris.
Date Control Link:** When using the **Open for Date** action, this property allows you to choose between having the Natal chart linked to the chart. Select a colour from the diamond grouping icon and a vertical line with that colour will appear on the price chart. As the green line is moved on the chart the ephemeris will also move to correspond to the date:
Line Brightness: Use the slider to adjust the brightness of the lines dividing the houses.
GMT Offset: Use this option to adjust the ephemeris time zone setting for a specific market. Select the required GMT setting and the ephemeris will automatically update.
Coordinate System: Changes the planetary positions based on equatorial or ecliptic coordinates.
Topocentric City: Set the required location for the ephemeris point of view. Select from a list of cities or add your own using Latitude, Longitude, and Altitude values under Custom.
