1. PLANETARY ORBITS MAKE BEAUTIFUL PATTERNS: The orbits of planets are just ellipses viewed heliocentrically, but from other perspectives they make beautiful patterns. Inspiring images of planetary orbits that demonstrate that astronomy is exciting, inspiring, awesome, and mysterious.
   
   
2. ASTROLOGY, CHAOS THEORY, and FRACTALS: Chaos theory can be used to help explain why the Ascendant and the Vernal Equinox (0 degrees Aries) are vitally important and why measurement along a Great Circle like the ecliptic plane may make sense. In short, chaos theory may help us understand some mysterious assumptions of astrology. Chaos theory and fractals can also help us discover new ideas. Other new insights into physics also suggest that we might be able to understand astrology primarily in terms of the structure of the universe and the resonances within it.
   
   
3. THE GRAPHIC EPHEMERIS IN SIRIUS 1.3: Tutorial video on using the graphic ephemeris in Sirius 1.3. Demonstration of viewing transiting, progressed, solar arc, and natal charts in a graphic ephemeris. How the same information can be seen in the graphic ephemeris and the time line. The Lifetime Declination Graph and transiting planets in latitude, as well as various customizing options, are also described.
   
   
4. ASTRONOMY FOR ASTROLOGERS, Part 1: Explanation of the astronomical foundations of astrology. This tutorial video was designed for astrologers but anyone interested in an introduction to positional astronomy may find this video helpful.
   
   Topics covered are: The diurnal motion of the planets through the houses, the proper motion of the planets through the zodiac signs, and the way the positions of the planets in the celestial sphere of the sky are presented in the two-dimensional chart wheel. The following terms are described and shown in a sky map representation of the sky: Zenith, Nadir, Horizon, and Altitude.
   
   
5. ASTRONOMY FOR ASTROLOGERS, Part 2: Explanation of the astronomical foundations of astrology. This tutorial video was designed for astrologers but anyone interested in an introduction to positional astronomy may find this video helpful.
   
   We learn what the ecliptic plane is and we see the position of the ecliptic plane change throughout the day. We learn what the astronomical definitions of the Ascendant, Merdian Plane, and the MC are. We see why astrological houses are different sizes, and we learn about azimuth and altitude and variations of the azimuth-altitude chart.
   
   The Sirius 1.3 astrology software is used to demonstrate the concepts. Sirius is created by Cosmic Patterns Software. The company website is http://www.AstroSoftware.com
   
   
6. ASTRONOMY FOR ASTROLOGERS, Part 3: Explanation of the astronomical foundations of astrology. This tutorial video was designed for astrologers but anyone interested in an introduction to positional astronomy may find this video helpful.
   
   In this video we learn (1) why the distance of a planet from the Ascendant is not the same as the distance from the horizon, (2) we learn about projected positions of planets on the ecliptic plane, and (3) we practice viewing planets in the Sky Map and estimating what the azimuth and altitude are, (4) right ascension and declination, and (5) the vernal and autumnal equinoxes, which are also the 0-Aries and 0-Libra points in the tropical zodiac.
   
   
7. ASTRONOMY FOR ASTROLOGERS, Part 4: Explanation of the astronomical foundations of astrology. This tutorial video was designed for astrologers but anyone interested in an introduction to positional astronomy may find this video helpful.
   
   In this video we learn (1) how to estimate the zodiac longitude and zodiac sign of a planet from its position in the sky, (2) what the latitude of a planet is, (3) what declination arcs and why planets with the same declination are referred to as a "parallel of declination", and (4) what the Prime Vertical and vertex are
