Hopefully the chart is legible. I've added several asteroids, including Harry and Megan (no "h").
In the chart we see all four axis in mutable signs, not optimal for longevity and stability.
I am just talking here, about what I see, about what you see.
Interesting, all being mutable, and only housing 2 Planets. Neptune/Pisces and Venus/Gemini
Harry is the ascendent and mercury, Meghan is the descendent and Jupiter/Neptune.
There is no contacts between Mercury and Neptune.
Moon approaching a sextile to sun is perfect for a wedding chart, and one of Harry's asteroids is conjunct the sun, which is suitable, him being the male and also royal.
Except for Algol being there
Meghan as Jupiter is conjunct the part of fortune, and she really did luck out with this marriage! And Harry is conjunct Jupiter, showing his commitment to the marriage.
This is so messed. Yes, she did luck out, but, POF is in tight opposition to Mercury/Harry.
This POF/Jupiter/Harry is trine the descendent/Neptune conjunction.
And we know he is completely besotted!
The Megan asteroid is exactly conjunct the descendent, and Neptune!
Eris is the asteroid of strife and discord, here conjunct another Harry asteroid, and square the moon (bride) so we begin to see some problems.
Amor and Juno, two other significant marriage asteroids, are conjunct on the cusp of the 8th of inheritance, and in fact the newlyweds live off the money they receive from the Crown.
So we have a tie between love and money.
This is apt.
The 8th is also sex, so this is a hint as to what their love tie is based on.
Vesta, asteroid of the hearth and home, is conjunct cold Saturn. Interesting that they spent millions on Frogmore, but don't live there!
The 5th is the children of the marriage, and we find Pluto and Lilith conjunct the cusp. Also in this house is mars on the south node. So much for an early and successful pregnancy!
I just noticed Jupiter, Saturn and Pluto are RX.
Harry as mercury is on the cusp of the 9th, overseas and philosophy and mind. He was near Uranus in the chart, and transiting Uranus is coming ever closer to a conjunction with him. And in fact we have seen photos of him nervous, upset, angry in several public situations, we can only imagine behind the scenes what takes place. Also, there is talk of them moving overseas, to the US or Africa.
Well, 3rd short distance travel and 9th long distance travel, seem to be in good form. Fixed, with Sun, Mercury, POF and Jupiter. But home has Saturn, but it is domicile. And the fourth is ruled by Sagitarrius, fiery fixed.
And lastly, we see Venus, goddess of love, in the last degree of her sign, square Chiron the wounded healer, who is in the 7th. By progression she will soon reach an opposition with the Vesta/saturn conjunction. Venus trines the vertex and widely squares poor Harry and Eris.
In a royal wedding we would expect Leo to be prominent, here it only holds the North Node. The midheaven is ruled by mercury, Harry's significator, which is befitting as he is the prince and the royal.
The continuous communications, the daily instagrams, the changes of plans, can be all explained by this MH in mutable gemini, as well as by the POF/Jupiter/Harry conjunction in the 3rd.
There are many more asteroids that could be inserted here, but it becomes less and less legible. But this is a start to have some insight into their relationship, and looking at this chart I would assume they followed instinct but not an astrologer!
