The leading design philosophy behind LUNA is to allow for intuitive navigation. This means that you don’t need to hunt for options through layers of menus. Instead, actions you want to take are presented to you at the appropriate time.
Creating biwheels (also known as synastry charts when these are associated with individual people), is an example of this. Be sure to create a radix chart and save it into your chart profiles before you begin to create biwheels.
LUNA supports creating biwheels between just about every kind of chart that can be cast. Use the guide below to see how to create a specific biwheel of your choice.
Biwheel Arrangement
You can re-order biwheels so that the inner wheel can become the outer wheel and vice-versa. Look for this “gripper” icon in the chart info panels and simply drag and drop the panels into the new order you prefer.
Drag this icon to move the info panels when it appears.
Radix Biwheel
Creating a radix biwheel (radix/radix or radix/transit) can be created as follows. Start by opening a chart from your chart profile or create a new one.
Radix & Radix (i.e. Synastry)
- [Desktop] Select “Synastry Biwheel” from the Chart Menu on the right.
- [Mobile] Expand the Chart Menu drawer at the top of the screen and select “Synastry Biwheel”.
- Select a radix chart from the list of chart profiles. A synastry biwheel is automatically created.
Radix & Transit
- [Desktop] Select “Transit Biwheel” from the Chart Menu on the right.
- [Mobile] Expand the Chart Menu drawer at the top of the screen and select “Transit Biwheel”.
- A biwheel between a radix and transit is created automatically.
Composite Biwheel
Creating a synastry biwheel between a radix (natal/event) chart or transit and composite chart can be created as follows. The composite chart you intend to add for the biwheel should be created beforehand and saved in your chart profiles.
Composite & Radix
- Open a composite chart from your chart profile.
- [Desktop] Select “Synastry Biwheel” from the Chart Menu on the right.
- [Mobile] Expand the Chart Menu drawer at the top of the screen and select “Synastry Biwheel”.
- Select a radix chart from the list of chart profiles. A composite and radix biwheel is automatically created. Note the radix chart is automatically placed in the inside position.
Pro Tip!
Two composite charts can be created as a biwheel if both charts are saved under your chart profiles.
Composite & Transit
- Open a composite chart from your chart profile.
- [Desktop] Select “Transit Biwheel” from the Chart Menu on the right.
- [Mobile] Expand the Chart Menu drawer at the top of the screen and select “Transit Biwheel”.
- A composite and transit biwheel is automatically created. Note the transit chart is automatically placed in the outer position.
For radix and composite charts, the desktop version of the “Add Biwheel” panel is shown on the left; the mobile panel on the right.
Other Biwheels
Biwheels can also be created between any of the Auxiliary Charts and their corresponding radix chart and even a transit chart.
The following instructions apply to all of the following chart types:
- Secondary Progressed
- Solar Arc Directed
- Return
- Relocated
Auxiliary & Radix
- Open a radix/natal chart from your chart profile.
- [Desktop] Select one of the auxiliary chart types from the Chart Menu on the right.
- [Mobile] Expand the Chart Menu drawer at the top of the screen and select the auxiliary chart of your choice.
- Select “Natal Biwheel” from the Chart Menu which will automatically create a biwheel between the auxiliary chart and the radix chart. Note the radix chart is automatically placed in the inside position.
Auxiliary & Transit
- Repeat the steps above to open any of the auxiliary chart types.
- Select “Transit Biwheel” from the Chart Menu. A biwheel between a transit and the auxiliary chart is created automatically. Note the transit chart is automatically placed in the outside position.
FYI
Biwheels between a radix and a relocated chart is not supported. This is because the planetary positions of both charts are identical and the only difference between these two charts are the angles and house positions of the planets.
