When it comes to synastry, I don't feel comfortable using 1 degree for anything orbiting beyond Saturn.

I believe that that the more distant,slower the object, the narrower the orb that it has to be. That's what I do with ecliptic longitude,Right Ascension,and Declination.

You wouldn't want a 1 degree orb for Sedna which has over 10,000 year orbit. a parallel or contraparallel would last many months...even over 1 year.

I think the declinations for synastry have to be be narrow when it comes to objects that orbit beyond Saturn.

I'd start with 30 minutes of arc with Uranus, and gradually decrease the orb

Neptune would get like around 20 minutes of arc

Pluto,Orcus,Ixion which are plutinos would probably use 10 minutes of arc. their orbits are within 246 to 248 years.

Eris would get around 5 minutes of arc with its orbit of over 530 years.

Makemake,Haumea,Varuna have orbits that are slower than Pluto and faster than Eris. 8 minutes of arc seem logical.

with Sedna,under 0 minutes of arc. It would be into the seconds of declination. In Right Ascension and Ecliptic longitude, I use only 5 minutes of arc for it in synastry.

I am not sure about using parallel,contraparallels with the lunar nodes.

it opens up a can of worms with nodes of other objects. if parallels and contraparallels can be used with lunar nodes, then they could be used with the nodes of other objects.

That's why I don't even look at declinations with the lunar nodes.

only the geocentric nodes of Mercury,Venus,Mars,and asteroids be used in synastry. the geocentric nodes of Jupiter and beyond move too slow,and they would be collective. All the heliocentric nodes move up to 1 degree per year. all of them would be collective.

the orbs would have to be considerably smaller for the nodes of other objects. I'd say 30 minutes of arc for natal. Synastry could be slightly less.

I am not sure if the houses work with declination because they are different coordinates. I feel the same about Right Ascension too. They are both equatorial coordinates unlike the regular zodiac which is ecliptical longitude.

Yes..you use angles.

Angles are independent of house system.

Cosmobiologists don't use a house system, and they use the Midheaven(they view the Midheaven/Imum Coeli axis as Midheaven) and Ascendant (they view the Ascendant/Descendant axis) just like view the North Node/South node as Node. They don't differentiate the angular separation of an aspect. That's why the equal sign tends to be used to denote an aspect. i.e.
Jupiter = Mars/Saturn.

You don't need house system to use the
angles.

The house systems like Equal and Whole Sign don't have the Angles as angular house cusps.
That only happens with quadrant house systems like Placidus and Koch.

The Midheaven/Imum Coeli axis and the Ascendant/Descendant axis always stay the same no matter what house system that you use.

other than for practical reasons (mass of info), is there a theoretical / logical reason behind not using parallels with the nodes?

So for synastry we use 1° for planets up to Saturn, and beyond that 30 minutes for Uranus, 20 minutes for Neptune, 10 minutes for Pluto and so on?

I can't think of any, but you can see if they work or not. The declinations of nodes might work with other objects too. The orbs should be smaller though.

"So for synastry we use 1° for planets up to Saturn, and beyond that 30 minutes for Uranus, 20 minutes for Neptune, 10 minutes for Pluto and so on?"

yes....gradually decreasing the orbs with the slower moving objects until you get to seconds of arc with Sedna.

I haven't used declinations with Vertex,but that doesn't mean that I don't think it's valid to use. If the Ascendant,Midheaven works with declinations, and I don't see why the Vertex can't. All 3 of them are points based on intersection of 2 planes.
