Preferences

LUNA allows you to customize many aspects of the software. To access your settings screen:

  • Login to your account if you're not already logged in.
  • [Desktop] Select your name from the upper-right of the screen or...
  • [Mobile] Select the "more" link (3 dots) from the upper-right of the screen.
  • A menu will display with a "Settings" link.
  • Select that link to access your personal preferences.

Your settings screen is organized into tabbed sections for easy navigation.

Settings Tabs

Home Location

You establish your home location when you login to your account for the first time. This location can be anything that is searchable in Google Maps. It's not necessary to use a specific address, and typically most people simply use the name of their city and state/province. You can, however, enter a point of interest such as "Statue of Liberty" or even the name of a hospital or business.

Important FYI

This information is kept private and is never shared with anyone. It is used only as a starting value for casting transit charts, so you don't have to specify a location each time you want to view the current transits.

Color Themes

LUNA comes with two (2) different color themes that can be changed anytime you like. The default theme is "Solar" and uses a brighter color palette. The "Lunar" theme is also very popular and great for viewing charts in dimmer lighting conditions.

This is a side-by-side comparison of the Solor & Lunar color themes.

House Systems

LUNA supports eight (8) different house systems:

  1. 0ยบ Aries
  2. Campanus
  3. Equal
  4. Koch
  5. Placidus
  6. Porphyry
  7. Regiomantanus
  8. Whole Sign

You can set the default house system from the Preferences tab of your settings screen. You can also change the house system on-the-fly whenever you're looking at a chart.

Info Panel

This info panel will appear for all charts. Selecting "Placidus" will take you to the Preferences tab of your settings screen where you can change the house system and return back to the original chart easily.

Parallax Moon (Locus)

Planetary positions are calculated from a geocentric perspective. The "Parallax Moon" option calculates the Moon from a topocentric (i.e. Earth surface) perspective. This setting can change the position of the Moon by up to about one (1) degree.

Note that LUNA does not take the location's altitude into account when calculating the Parallax Moon. This can result in a difference of about two (2) arc seconds when at an altitude of 3,000 meters.

Lot/Part Calculations

LUNA can calculate two (2) of the Lots/Parts:

  1. Lot/Part of Fortune
  2. Lot/Part of Spirit

These are calculated points based on a combination of the Sun, Moon and Ascendant of the chart. You can indicate which calculation method you prefer by selecting from the options provided:

Respect Diurnal/Nocturnal (sect)

This option will take the sect of the chart into consideration when calculating these points. Thus for a diurnal (daytime) chart, the standard equation for Fortune is used:

Ascendant + Moon - Sun

For a nocturnal (nighttime) chart, however, the inverse of this equation is used:

Ascendant + Sun - Moon

The same calculation rules apply to Spirit also.

Ignore Sect (fixed)

This option will ignore the sect of the chart and use the standard equation for both Fortune and Spirit at all times.

Planetary Nodes

When viewing planetary nodes on your charts, LUNA can calculate them from a geocentric or heliocentric position. Note that the north and south heliocentric planetary nodes are always 180° apart from one another.

However, geocentric planetary nodes are not necessarily separated by this same distance. This is because the nodes represent the planet's orbit as it intersects the ecliptic, which from Earth's perspective does not necessarily occur at opposite points of the zodiac.

Tropical/Sidereal Zodiacs

The default zodiac for LUNA is the tropical zodiac. LUNA also supports sidereal calculations for all charts. Simply choose from one of the available eight (8) ayanamsas:

  1. DeLuce
  2. Djwhal Khul
  3. Fagan-Bradley
  4. Krishnamurti
  5. Lahiri
  6. Raman
  7. Usha-Shashi
  8. Yukteshwar

Info Panel

When viewing charts using the sidereal zodiac, LUNA will display the ayanamsa in use in the chart info panel. You can easily switch between zodiacs by selecting the zodiac name which will take you to the Preferences tab of your settings screen.

Composite Midpoint Base

When calculating composite midpoint charts, you have the option of basing the houses for the chart on either the Ascendant or the Midheaven. The reason this is important is because composite midpoint charts are not "real" charts. This means they don't represent a time and place like most other charts (specifically radix/natal charts).

Since they are a calculated chart based on the midpoints of two (2) other charts, sometimes the calculations of the houses are incoherent. For instance, it's possible the midpoint of the 2nd house doesn't follow the midpoint of the 1st house in zodiacal order.

In order to account for this, LUNA needs to know which of the angles you want to use as the base of the houses:

Ascendant

The midpoint of the two (2) ascendants will be used as the ascendant of the composite chart. All other midpoints between the houses will follow in zodiacal order.

It's possible the 2nd house (and all others) of the composite chart could actually be the composite midpoint of a totally different house.

Midheaven

The midpoint of the two (2) midheavens will be used as the midheaven of the composite chart. All other midpoints between the houses will follow in zodiacal order.

It's possible the 11th house (and all others) of the composite chart could actually be the composite midpoint of a totally different house.

Good to Know

Please note that although it's possible to calculate two (2) different composite midpoint charts based on this setting, very often you will see the same chart regardless of which setting you choose. You can experiment with this setting on all your composite midpoint charts to see which ones are affected by it.
