On level 14 how do i complete the zodiac puzzle in the obseratory?

there are 3 rotative disks. one button acts on the big one and the smallest one. the smallest one rounds faster than the big one. so it will probably take u two rounds, untill the scorpio sign is around 12 o clock, and the sign of juno(i think, there's also a map on the right indicating u which signs means what ) is on the same line with the scorpio sign. after that u have to put the jupiter sign(i also think this is the name, check the map there if u forget ) also on the same line with the first two. there are 2 same signs, one with black background, other with white. the one with white must be fixed right behind the 2 signs mentioned before; and then, a scene should interact and show u which gate will open
