Many astrologers analyze a chart wheel with multiple rings and in the rings there may be a natal chart, a progressed chart, transits, and another kind of progressed chart or directed chart, or a solar return or other kind of chart. There are many variations of these chart wheels and kinds of progressions and returns. Described below are many of these features that are available in Kepler, and we describe the features in three sections:

• Progressed Chart Wheels and Calculations
• Returns, Phase Angle Returns, Diurnals, etc.

Secondary progressions (also known as day-for-a-year progressions) are probably the most popular form of progressions but there are other kinds of progressions. Also, there are different methods for progressing house cusps. Note that these different methods of progressing houses are different even for the same house system (Placidus, Koch, whole sign, etc.) In order to meet the needs of as many astrologers as possible, Kepler offers a large number of progressions and methods of progressing houses. Because you set your default preferences, these additional choices do not slow you down or get in your way.

The methods available for progressing houses are Naibod in R.A., Solar Arc, Mean Sun, Time, Quotidian with Bija Correction, Quotidian without Bija Correction, Fagan-Naibod, Quotidian Mean Sun, and PSR (Progressed Solar Return) Method. Even most advanced professional astrologers are not familiar with all of these options but they are available if you want them. To learn about some of these progressed methods, you can watch the video on Different Methods of Calculating Progressed House Cusps. Also in Kepler's Help system we have documented the accuracy of these calculations by comparing the results produced with classic astrological works, and we explain how these methods are used by the astrologers who developed and promoted them. Kepler is much more than just a program that lists a lot of fancy options that you can select. We also provide information to show that the calculations are accurate and instructional material on how astrologers use the methods.

Note that there are many other kinds of progressed methods in Kepler such as the classical primary directions, Hellenistic time lords, etc. but these methods are used to produce listings and tables and not chart wheels. Here we are discussing just progressed and return chart wheels.

BiWheel

Multi-Ring and Multi Wheel Styles
A Multi-Ring wheel can have house cusps that are equally spaced are are drawn in the size of the house cusps in the inner ring. Zodiac sign areas may be included around the outer edge if desired. For BiWheels only you can also have each wheel have its own house cusps. You can also select a smaller wheel with an aspect grid or a larger wheel without a grid next to it in the same window. You can also select a Dial format (like a 90 Degree Dial for example) with an interactive dial arrow that you can rotate to show the midpoint structures that are formed. Some astrologers prefer separate wheels rather than multi-ring wheels and you may place up to four wheels in one window.

One issue with Multi-Ring wheels is the ability to see the minutes of the planet positions. For example, suppose that one planet is at 3 deg 01 min of a sign and another planet is at 4 deg 59 min of the same sign. The two planets are almost 2 degrees apart. On the other hand if one planet is at 3 deg 59 min and the other planet is at 4 deg 00 min the 2 planets are nearly in exact conjunction. Some astrologers use Multi-Ring wheels without the minutes of arc and this runs the risk of not being able to see what the actual orb of an aspect is. In Kepler all Multi-Ring Wheels by default include minutes and they are readable, but you can remove the minutes very easily and set this as your default if you prefer (although most astrologers do not choose to do this).

Note that it is very easy to put any charts in a Multi-Ring Wheel, such as one person's natal chart, and another person's progressed chart, or natal charts of 2 people and their composite chart, or the geocentric and heliocentric charts of the same person.

Natal and Phase Angle Return

BiWheel: Natal and Phase Angle Return

Many astrologers are familiar with Solar and Lunar Return Charts. There are many variations of these charts that astrologers use. Some of these variations and similar kinds of charts are:

• Planet returns such as a Mercury Return, Venus Return, etc.
• A return of one planet to another, such as the transiting Moon conjunct natal Sun
• A demi-return, etc: An example of this is the time that the transiting Sun is opposition natal Sun. You can easily select a series of returns such as, for example, the four returns of conjunction, waxing square, opposition, and waning square.
• Precessed Returns: Calculated using sidereal methods but shown in the tropical zodiac
• Phase Angle Return: When two transiting planets form the same angle as in the natal chart.
• Diurnal Chart: A chart for the time you were born on any day. There are four variations of this chart: Same Time, Same Sun-Asc Angle, same Sun-MC angle, and same Sun-MC angle in right ascension.
• Converse Transit: Chart for how old you but before birth.
• Converse Solar, Lunar, and Planet Returns: The return occurring at the time before birth equal to the age at the time of the converse return.
• Tithi Return: A return used in Vedic astrology which is a Sun-Moon phase angle return with either the Sun or Moon in same sign as in birth chart.
• PreNatal Lunation, New Moon, or Full Moon
• Conception Chart based on the rules of E.H. Bailey.

We plan to expand this section and make tutorial videos on many of these methods. If you need more information, let us know and we will add more information here or make some tutorial videos.
