This article covers the basics of synastry chart compatibility, the aspects between two charts and the midpoint-in-time, Davison relationship chart. You can also look further into synastry astrology in Best Synastry Aspects and also see the test I devised for my Synastry readings in action with the Soulmates Love Test article.
Finding true love with a soulmate is not all that it’s cracked up to be. It’s more likely to be a case of “Help, I’ve found my soul mate!” In synastry astrology, the 7th house is not just the house of marriage, it is also the house of open enemies. It is also opposed the 1st house of the physical self. Therefore the supposed “Soul mate” relationship is very often a tug of war on many levels. What may feel destined could also be a number of things. The beloved could be reflecting strongly back to you your animus or anima, what you are lacking in your chart, what you have disowned in your chart or, when the relationship turns sour, your worst demons.
With synastry chart compatibility, squares and challenging synastry aspects between a couple are karmic aspects and can be extremely challenging. These will usually enable you to “fast-track” your spiritual evolution by burning off a ton of ingrained karma. Often a soul mate comes into your life simply to do this, but it does not mean it is life long. Negative karma from the past can attract you even more strongly than positive karma. Hence those impossible, gut-wrenching, and often unrequited love affairs.
I don’t believe an Astrologer can or should ever tell you “This is THE one”. It could be “A” one however, and they can certainly show you exactly why you have been pulled together. You will also be able to see why you find it so hard to break up even if the relationship is making you miserable. Usually these are Moon/Saturn contacts.
Looking at the charts individually first is crucial to see what each person can handle in a relationship. Some people just cannot take too much drama, others would be bored without it. Some may need a very cosy domestic 24/7 togetherness, while others crave space, so that a long distance romance might actually suit. Therefore it’s really rather pointless saying “Oh my Sun is conjunct his Moon, we are destined!” if one of you is a thrill seeker and the other likes vegging infront of the TV.
Davison Synastry Chart
Relationships are the best teacher and love horoscope compatibility using synastry aspects can certainly see what type of lessons you are learning from each other. There are 3 ways to do this, and that is through casting the Composite, Davison and Draconic charts.
One of the most illuminating things to look out for, is when the partners important planets or points make a conjunction with the Sun, Moon, AC, Nodes or Vertex in the Davison chart. It shows how important the relationship is for each of them. It will reveal if one is more attached to the union than the other.
The Davison compatibility horoscope takes the midpoint in time between the couples birth-date. The co-ordinates are also half way. This is my specialty. I love Davisons because this chart actually exists physically, so one can take into account the fixed stars. I have also found them to contain the most magic. This chart describes why you have been brought together and what lessons you have to learn in this lifetime.
With the fixed stars, you can sometimes get a very clear picture of the past lives and karma that brought the couple together. With Soulmates it is usually very obvious. Symbols and themes will keep repeating themselves and a story will come out. The Tarot which is looked at with the Nodes will often confirm this. It is very important to look at the connections from the Davison to the couples natal charts. Strong indicators of many lives together and/or a karmic mission will be confirmed if the couple have conjunctions to the big 3 (Sun/Moon/AC). We have found the Nodes and the Vertex very important also.
Davison Chart Example
The big stand-out theme in our the Davison chart with my husband Jamie is the fact the tight North Node/Vertex conjunction in our synastry falls on the Sun of the Davison. Important synastry between the couples own birthchart’s and the Davison is crucial to dittermine if the relationship itself is important to them both. In our Davison chart the big feature is that the Sun is tightly opposed the Moon (27′) which means our SouthNode/Anti-Vertex falls on that Moon too making it all the more potent.
What is lovely about Huber charts is they do paint pictures, this is deliberate and is counted as part of the interpretation. In this we get what looks like two sail boats, the larger one containing the important Sun opposite Moon. It looks like the two of us voyaging along the astrological sea, the fixed stars above us serving as guides. It also looks rather like Sydney opera house!
I like the fact that travel is a theme with Jupiter in the first boat, very apt since we live 10000 miles apart. In the second boat we have Mercury (writing), Venus (art/love) and Mars opposite Lilith (sex & war) which describes our website pretty much. Look at abundant Ceres and Jupiter in the 5th. 4 kids between us, but also a fertile ground for creativity.
The closest star to the all important Sun is on is Mirfak in Perseus. This is the arm that cut off Medusa’s (Algol) head, we both have our demons to slay, and part of our mission with Darkstar is to help other address their own. I do see Perseus as some sort of exorcist. Further away but more important as a star is Alcyone (The Pleiades) on our Sun. Again it is another one of those Darkstars with a mixed reputation. “The ruthless visionary, a passionate but potentially arrogant person.” . In my research I found Alcyone to be wise and magical, but it’s true it has not been an easy ride for us both. We have had our share of scandal and rockiness in relationships.
The rising star in the chart will show our souls journey and the impression we give to others. The closest star is Biham on the face of our friend Pegasus. Pegasus was born of Medusa’s blood. This connects with our Sun, heroic Perseus. If we can slay our demons both personally and in our work, we can reach for the stars like Pegasus.It also suggests ambition and long distance travel. More Pegasus, I like Chiron the Astrologer up front in the 1st house sitting on controversial Scheat! Chiron is sextile our Sun. There is no escape from the Astrology then, Uranus in the 7th, a married couple who are Astrologers also. We do battle however, Mars square Venus can be stressful in a working relationship with a spouse. Competitive, but creative. Venus will tend to win because she is on the brightest star in the sky Sirius. Mars can be tricky on Algorab... I was very pleased to see that we had Antares the heart of the Scorpion and Archangel star on the MC with Alderbaran, Archangel Michael on the IC protecting us.
Fortunate aspects to the luminaries are important, and we have Jupiter’s blessing (A trine to the Moon) to the competitive Sun/Moon opposition, we do need that because those very archetypical Sun/Moon, Venus/Mars hard aspects certainly show some sort of battle of the sexes. Not showing up here because its a Huber chart is the fact Lilith is opposite Mars too! Also not showing, a mystic rectangle with the Nodes and AC/DC and a high flying kite between the Sun/Moon/Jupiter and Chiron.
Davison charts often show very clear karma between a couple and clues to their past lives. I’m pretty sure Jamie and I have worked together before, I also think we have always had the issue of work/family balance also. (Mars square Ceres). The best synastry in the world however does not guarantee ever-lasting happiness. I show our chart here as a good example of a life changing and catalystic relationship. It’s a very strong and dynamic chart, but not necessarily an easy one.
Looking at our synastry with the Davison. It is interesting that my AC is 2 degrees off our Mercury (Writing/Astrology) on Rigel “Scientific, prominent position in connection with Mercurial matters or in science.”  While Jamie’s DC is our Ceres (The children). Our challenge is the reversing of traditional roles, as a single father of three young children, Jamie has had to take the role of the mother. I, on the other hand, am very much used to my independence. Having only one child and free weekends leaves me much time to write. When we finally live together, all this will change. Can this chart take on the challenge?
