What Your Full Compatibility Reading Covers
Every couple exists on three levels simultaneously. There is who you are as individuals. There is the chemistry between you — the pull, the friction, the places where you fit and the places where you catch. And then there is the relationship itself: the third entity that came into existence the moment you came together, with its own character, its own needs, and its own trajectory that neither of you controls alone.
Most astrology services read one of these levels and call it a compatibility reading. A synastry reading covers the chemistry. A composite reading covers the relationship entity. Neither alone gives you the full picture, because neither alone tells you how the chemistry between you shapes the entity you have built — or how the entity’s nature amplifies or complicates what the chemistry would otherwise produce.
The Nuastro Full Compatibility Reading covers all three levels in a single integrated analysis — calculated entirely using real-sky IAU constellation boundaries. This is our most comprehensive relationship reading, and it is the only one we offer exclusively in the real-sky format. Here is everything it includes:
Part One: The Chemistry — Your Real-Sky Synastry Analysis
- Every significant interaspect between both natal charts — all major contacts between your planets and theirs, calculated from real-sky IAU positions
- Sun-Moon contacts — the axis of deep attunement, where one person’s core self meets the other’s emotional interior
- Venus and Mars interaspects — the full picture of attraction, desire, and how affection and drive interact across the two charts
- Saturn contacts — where commitment, weight, and long-term staying power live in the connection
- Outer planet contacts — Uranus, Neptune, and Pluto aspects that describe the transformative, destabilising, or fated dimensions of the bond
- Lunar node contacts — north and south node connections indicating karmic threads and the direction the relationship pulls both people toward
- Angle contacts — any planet conjunct the other person’s Ascendant, Descendant, Midheaven, or IC, among the most personally felt connections in any synastry reading
- Ophiuchus interaspects — if either person has planets in Ophiuchus by IAU boundaries, all contacts to those placements are identified and interpreted in full
Part Two: The Entity — Your Real-Sky Composite Chart Analysis
- The composite Sun — sign, house, and aspects: the relationship’s core identity and the central energy it generates
- The composite Moon — the emotional interior of the relationship, how you make each other feel at home or unsafe
- The composite Rising sign — how the relationship presents itself to the world and the role it plays in both lives
- All composite planetary placements — every planet in the midpoint chart interpreted in its house
- Composite Venus and Mars — the relationship’s approach to love, desire, and conflict as a unit
- Composite Saturn — the weight, commitment, and structural spine of what you have built
- Composite stellia and house concentrations — any house with three or more composite planets interpreted as the relationship’s dominant focus
- Ophiuchus in the composite — if composite planets fall in Ophiuchus by IAU boundaries, the healer archetype and its role in the relationship’s identity is interpreted in full
Part Three: The Integration — Where Chemistry Meets Entity
- A dedicated synthesis section connecting the synastry and composite layers — showing how the chemistry between you shapes the relationship entity, and how the entity’s nature channels or distorts the chemistry
- Recurring patterns — themes that appear in both the synastry and composite charts, indicating the relationship’s deepest and most consistent dynamics
- Tensions between layers — where the synastry suggests one thing and the composite suggests another, and what that contradiction is likely producing in the lived experience of the relationship
- The relationship’s central question — stated plainly: what this bond is fundamentally asking of both people, and what it is most likely building toward
- A closing guidance section — not predictions, not prescriptions, but honest and specific observations on what this relationship needs most from both people to move toward its best version of itself

This reading is offered exclusively in the Nuastro real-sky format. We do not offer a tropical version of the Full Compatibility Reading. The reason is straightforward: a reading of this depth and integration requires the most astronomically precise foundation available. Using IAU constellation boundaries for both natal charts — and therefore for both the synastry interaspects and the composite midpoints — ensures that every placement, every contact, and every midpoint in this reading reflects where the planets actually were in the sky. At this level of analysis, precision is not optional.
How to Order Your Full Compatibility Reading
Your reading costs $74.99. You will need the birth date, birth time, and birth location for both people. Birth time accuracy matters significantly at this level — the synastry angle contacts and the composite Rising sign both depend on it, and these are among the most personally felt placements in the entire reading.
If one person’s birth time is genuinely unknown, let us know when you order. We can still produce a thorough reading — the planetary interaspects and composite planets remain fully valid without a birth time — but we will note where the interpretation is approximate and shift the emphasis accordingly. If both birth times are unknown, reach out before ordering and we can discuss what is possible.
When you order, a brief note about the relationship context is helpful — how long you have been together, whether it is a romantic partnership, and any specific questions or patterns you are most curious about. We do not require this, but it helps us orient the synthesis section toward what is most relevant for you.

Why This Reading Requires the Real Sky
Every other reading in the Nuastro service catalogue is available in both real-sky and tropical formats. The Full Compatibility Reading is not. This is a deliberate decision, and it is worth explaining why.
A compatibility reading of this depth works across three analytical layers simultaneously: the individual natal charts of both people, the synastry interaspects between them, and the composite midpoint chart. Each layer is built from the same source data — the planetary positions at each person’s birth — and any imprecision in that source data compounds across all three layers. A one-degree shift in a natal Venus, for instance, changes not only that person’s natal interpretation but also every synastry aspect that Venus makes to the other chart, and the midpoint position of the composite Venus.
The tropical zodiac is a symbolically rich and internally consistent system, but it is no longer aligned with the actual sky. The precession of the equinoxes has moved the tropical signs approximately 23–24 degrees away from the real constellations. At the level of a single natal chart reading, this is a philosophical difference — tropical and real-sky are simply different frameworks. At the level of a full three-layer compatibility analysis, it is a precision question. When we are identifying interaspects to within 2–3 degrees and calculating composite midpoints to a single degree, the most astronomically accurate positions available produce the most reliable reading.
The real-sky system also surfaces Ophiuchus placements that the tropical system cannot access. In a compatibility reading, Ophiuchus contacts between two charts — or an Ophiuchus composite planet — carry a specific and significant quality that would be invisible in a tropical analysis. A relationship whose composite Sun falls in Ophiuchus is a relationship fundamentally structured around healing, threshold-crossing, and the kind of transformation that only comes from going through something together. Identifying and interpreting that quality is part of what makes this reading complete.
The Three Charts of Every Relationship
To understand why a full compatibility reading requires three levels of analysis rather than one, it helps to understand what each chart is actually measuring — and why none of them alone tells the whole story.
The Two Natal Charts: Who You Each Are
The foundation of any relationship reading is an accurate understanding of each person individually. Before asking how two people interact, a thorough reading asks: who is each person? What does each one need from love? How does each one express affection, handle conflict, and approach commitment? What are the core patterns each brings into every relationship they enter — not just this one?
In the Full Compatibility Reading, we do not simply overlay the two charts immediately. We begin by establishing the relevant dimensions of each natal chart — the Venus and Mars placements, the Moon sign and house, the seventh house structure, the Saturn placement — so that the synastry contacts are interpreted in the full context of each person’s individual relational patterns. Two people can have the same Venus-Mars synastry aspect and experience it completely differently depending on the natal condition of each planet in each chart.
The Synastry Layer: The Chemistry Between You
The synastry analysis overlays both natal charts and maps every significant contact between them. This is the layer that describes the interpersonal dynamic — what happens in the space between you. The attraction, the ease, the friction, the places where one person consistently activates something in the other. The contacts that feel fated. The contacts that are simply fun. The ones that produce recurring conflict regardless of both people’s best intentions.
Synastry, as codified in the modern era by astrologers including Robert Hand and Stephen Arroyo, answers the question: what does this specific person activate in you, and you in them? It is a portrait of the chemistry — and chemistry, as anyone who has been in a relationship knows, is real but not sufficient. Which is why the next layer matters.
The Composite Chart: The Relationship Itself
The composite chart is calculated from the mathematical midpoints of both natal charts — the midpoint of both Suns becomes the composite Sun, the midpoint of both Moons becomes the composite Moon, and so on. The result is a single chart that belongs to neither person individually. It is the chart of the relationship as an entity in its own right.
This is the chart that answers: what is this relationship for? What is it organised around? What does it want from both people? Where does it have natural staying power, and where are its structural vulnerabilities? The composite chart describes the container — the relational space the two of you inhabit together — independent of the chemistry that brought you there.
Pioneered in its modern form by John Townley and further developed by Robert Hand, the composite chart remains one of the most consistently reliable relationship analysis tools in contemporary astrology. Its central insight — that a relationship has its own nature, which is not simply the sum of two people’s natures — is one that almost everyone who has been in a significant relationship recognises immediately.
The Integration: Where the Two Layers Speak to Each Other
The most valuable section of a full compatibility reading is one that most services never attempt: the integration of synastry and composite into a single coherent analysis. This is where the reading moves from description to insight.
The synastry tells you there is intense Venus-Mars chemistry. The composite tells you the relationship has a twelfth house Sun — a bond oriented toward the private, the spiritual, and the hidden, not toward public life together. The integration tells you: this is why the attraction is so powerful and why the relationship struggles to find a stable external form. The chemistry is real. The container the composite has built is not one that expresses easily in the world. That tension is the relationship’s central challenge, and naming it is the first step toward working with it rather than being confused by it.
This kind of cross-layer insight is what makes the Full Compatibility Reading genuinely different from simply receiving a synastry report and a composite report side by side. The integration is where the reading becomes a tool for understanding — and potentially for conscious navigation of where the relationship is and where it wants to go.
What This Reading Can and Cannot Tell You
A compatibility reading of this depth can tell you a great deal. It can tell you the nature of the chemistry between you — where it is strong, where it is complicated, and why certain dynamics keep recurring. It can tell you the character of the relationship entity you have built and what it is fundamentally organised around. It can tell you where your individual patterns reinforce each other and where they create friction. It can name the relationship’s central question and give you a clear-eyed account of its genuine strengths and structural vulnerabilities.
What it cannot tell you is whether you should stay together. Whether the relationship will last. Whether the person you are with is “the one.” Astrology describes the terrain — it does not navigate it for you. The chart is honest about what is there. What both people choose to do with what is there is always, entirely, a human decision.
This matters to say clearly because the most common reason people order a compatibility reading is that they are in some kind of uncertainty or difficulty and they want an answer. The reading will not give you an answer to whether to stay or go. What it will give you is the clearest possible picture of what you are actually dealing with — and that clarity, in our experience, tends to be more useful than any answer we could provide.
Frequently Asked Questions
Why is this reading only available in the real-sky format?
A three-layer compatibility analysis built from two natal charts, their synastry interaspects, and a composite midpoint chart compounds any imprecision in the source data across all three levels. Using IAU constellation boundaries for both natal charts gives us the most astronomically accurate planetary positions available, which produces the most reliable interaspects and composite placements. At this level of depth, precision is not a style preference — it is the foundation the reading rests on. We also do not want to offer a reading that identifies Ophiuchus contacts as a core part of the analysis in the tropical version where they would simply not exist.
What if my partner is sceptical about astrology?
That is not a problem for the reading. You can order with only one person’s enthusiastic participation — the analysis is equally valid regardless of whether both people believe in astrology. Many people find that sharing the reading with a sceptical partner is itself an interesting conversation. The reading describes what is actually there in the charts. Whether the two of you find it resonant is a separate question.
Can I order this for a relationship that has ended?
Yes, and many people do. A full compatibility reading of a past relationship — particularly one that was significant, confusing, or painful — is often the most clarifying reading of all. Understanding the synastry chemistry and composite entity of a relationship you have already lived through tends to produce the kind of retrospective clarity that is otherwise very hard to reach. The charts do not expire when the relationship does.
Is this reading suitable as a gift for a couple?
It is one of the most meaningful gifts you can give to a couple who are open to it. At checkout, include both people’s birth details and the email address to deliver to. Many couples find that receiving a reading of this depth together — and discussing it — is itself a clarifying and connecting experience. It functions as a portrait of what they have built, and most people find that kind of mirror genuinely valuable.
How does this compare to ordering a synastry and composite reading separately?The standalone synastry reading and composite reading are each thorough single-technique readings at $24.99 each — $48.98 combined. The Full Compatibility Reading at $74.99 adds the integration layer, the Ophiuchus contact analysis across all three charts, the relational natal analysis section, and a significantly longer and more synthesised document. If you want the deepest available picture of a relationship, this is the reading built for that.
