Speak with the Observatory professor, located in the reception room of the Observatory near the Observatory tower, north of Castle Wars. Ask him about the Observatory and he will mention that goblins have recently moved in and tampered with its telescope. To repair it, he needs three planks for the tripod, a bronze bar for the tube, and molten glass for a new lens.

Talk to him again three times, and he will take each item from you. Once you give him the final item, he will mention you also need to retrieve a mould for the new lens that has been stolen by goblins. Make sure the professor has taken all of the items before continuing, otherwise you will need to repeat the next section.

Note: If you don't have a form of antipoison, you can pick up a superantipoison at a spawn in the corner of the south-eastern building near Greasycheeks and Smellytoes's fire.

Go down the stairs to the east of the reception room to find the Observatory Dungeon (the room with the stairs is directly east of the start point). Once down the stairs, you must find the goblin kitchen key. It is commonly found in the south-eastern most chest although it can vary from person to person. Search any chests you pass on the way to the south-eastern chest just in case. Once you search the correct chest, complete the dialogue or you won't receive the key.

Note: Sometimes there may be a poisonous spider (level 31) inside the chest.

With the key, follow the north-eastern path west to the kitchen gate. "Prod" the sleeping guard (level 42), who will wake and attack you. Kill him or get him stuck behind a wall and you will be able to pass through the gate.

Note: Getting him stuck will cause him to attack you again when you leave, and another sleeping goblin will spawn.

Open the kitchen gate, consuming the key, and then inspect the goblin stove. You determine the goblins are cooking something foul in the lens mould. Dump out the stew and bring the mould back to the professor.

After speaking to the professor, his assistant will interject and ask you to make the new lens yourself as the professor has a history of explosions when attempting to craft things.

Use the molten glass that the professor just gave you with the lens mould to craft him a new lens. Give it back to the professor. He will want you to visit him in the Observatory.

Climb back down the stairs into the Observatory Dungeon. Now follow the north-west passage (past the kitchen) to find some stairs leading to the Observatory (the southern set of stairs on the map). There is also a chest north-east of the stairs to the Observatory, which spawns infinite Antipoison(1) vials, which you can combine to make full vials.

Go up the stairs, and a cutscene will play. If the cutscene does not play, you may have forgotten to give the finished lens to the professor. After the cutscene ends, go up the stairs and talk to the professor, and then "view" the telescope to see a constellation.

After closing the window, the professor should ask you which constellation you saw. The constellations are on wall charts in the main level of the Observatory. Identify your constellation, talk to the professor again, and you should get your reward in your inventory.

Congratulations, quest complete!
