All of my personal planets except for 4h Jupiter in Scorpio are conjunct. I have 3 planets in the 7th house and 3 in the 8th house, all consecutively conjunct one another. 4 of the planets are in Aquarius, 2 in Pisces. The Sun is the connector between the two houses, conjunct the 8th house cusp by 3 degrees and definitely felt mostly in that house (though 7th is felt also).
(Aquarius) 7Mars cj 7Moon cj 7/8Sun cj 8Venus cj (Pisces) 8Saturn cj 8Mercury
The kicker is that Jupiter squares everybody in the configuration (0degrees square to Moon, yay) except for Mercury, who thankfully gets a trine.
I've had a ton of trouble figuring it out, although now that some pieces have fallen into place it makes more sense. 4th, 7th, and 8th house themes dominate my life. Sun and Moon sextile the Midheaven (with Lilith conjunct within 1 degree), so that brings the 10th house into reasonably heavy play also.
People have always described me as very 'intense' (though pleasant, which seems a strange combo!). I also have Pluto in Scorpio 2 degrees conjunct the NN(on the 29th degree) quintiling Mars and squaring the rest of the stellium, and with that Lilith on the midheaven. Pluto and Mars both aspect the ascendant, the first by trine, the second by opposition. Well. You get the picture.
Definitely not the most planets in a stellium but man, let me tell you these stelliums run me ragged. I love them though now that I'm beginning to understand myself~
