Regarding the Algol/Uranus situation:
Some authors-including Robson-allow that stars can affect via opposition (if close), and sometimes close square (not, though, via soft aspects like trine and sextile)
I do not follow this outlook although I immediately say that I do not necessarily dispute it: just that conjunction and Parallel has been so important for me in looking at stars via planets, that I have had not motivation to look into aspects fromr stars to planets (oppositions, squares)
On a more general note, do not forget to check in possible Parallels regarding the relationship of natal planets with each other; remember that any close Parallel of declination (within 1.5 degrees) is equivalent to a strong conjunction of the planets involved.
