Where to find the Planetarium Floorplan in Blue Prince
The Planetarium is a hidden room accessed through the Observatory. To find the Planetarium floor plan, first head to the Observatory. Inside the Observatory, a player needs to interact with two dials. First, turn the lower dial to spin the telescope almost all the way around—point it toward the ledge above you.
Then, go upstairs and use the small upper dial this time. You need to use the small dial in such a way that it will stretch the telescope out toward that same ledge where you are standing.
Once it’s lined up, interact with the telescope, and a hidden compartment will open.
This hidden compartment contains the Planetarium floor plan.
