The Orrery - Planetarium Puzzle (Part 1)

This sequence is also shown in a short video walkthrough.

This is less of a puzzle than a platforming challenge, but you will need to rearrange a few of the pieces of the elaborate mechanism in order to reach the top. Start by walking out onto the wooden beam.

Shoot a rope arrow into the nearest rope-wrapped orb...

...to pull it toward you.

This rotates the armature from which the orb is hanging. Now you can jump onto it.

Walk to the far end and jump down onto the circular platform at the center of the orrery.

Now take a look at the moving parts. On the east side of the room are 2 taller armatures. One has an orb and a set of metal grapple rings.

Shoot the orb once...

...to pull it toward you.

This rotates the armature a quarter turn.

Move around to the right a little.

Then shoot that same orb again.

This rotates the armature another quarter turn, so the grapple rings point toward the southeast corner of the room.

Now let's do the same thing with the other tall armature. This one has an orb at one end and a wooden board at the other.

Shoot the orb to rotate the armature a quarter turn.

Do the same thing again to rotate the armature another quarter turn.

When you're finished, the grapple rings should be closest to the southeast corner, and the wooden board should be near the two red-and-gold banners hanging on the east wall.
