So ... opposition = 2H = 12 divided by 2 = 6 degree orb (for oppositions)

... trine/3H = 4 degree orb ... square/4H = 3 degree orb ... quintile/5H = 2 deg 24min orb ... sextile/6H = 2 degree orb ... septile = 1 deg 42 min 51 sec orb ... octile/8h = 1 deg 30 min orb ... 9H = 1 deg 20 min orb ... 10H = 1 deg 12 min orb ... 11H = 1 deg 5 min 27 sec orb ... 12H = 1 degree orb.

This works ok up to the 30th Harmonic (30H) ... but tighter orbs are needed for harmonics higher that the 30H.

At astro.com though, I think the orbs cannot be changed to those recommended by John Addey ... So, use an orb factor that produces a 3 degree orb for all aspects ... That way, the square aspects in H1 to H30 are correct - and it is not difficult to mentally increase/decrease the orbs for conjunctions, oppositions, trines and sextiles.
