Walkthrough

Starting the quest

Talk to the Observatory Professor and ask to look through his telescope. He tells you that the Goblin residents have been causing trouble and tampered with it. He asks you to collect 3 different items. Hand in all 3 items, and he will return the molten glass while asking you to find the lens mould.

Go down the ladder in the Observatory post, into dungeon. Go through the maze to the far south west corner and you find a chest containing a keep key. Go to the room where a level-48 Goblin guard is (labeled "keep" on the map), kill him before using your key on the gate (or else the key will be broken and discarded, which you will have to get another one again). Search the sacks to find lens mould.

The Goblin guard does not need to be killed in order to open the gate. It is possible to simply fight him for the first 3 mandatory rounds of combat, retreat and quickly use the key on the gate, which will allow you to pass through it.

Go back to the Observatory post and give the lens mould to the Professor. Agree to help him make the lens. Use molten glass on the lens mould and then talk to the Professor and he will tell you to meet him in the Observatory.

Telescope

Go back down to the dungeon, and through the maze. Find another ladder, to the north of the chest containing the keep key. It leads to the telescope. Talk to the Observatory Professor and look through the telescope to get a constellation - if you would like to choose a specific constellation for a specific quest reward, keep re-using the telescope without discussing the results with the professor or asking him about the constellation. The constellation chosen will be random every time.

After discussing the results with the professor, he'll tell you that you're blessed by the gods, and you will receive a reward depending on the constellation you picked.

Optional: Unholy symbol mould

Grave of Scoprius

Speak to the Spirit of Scorpius, at the graveyard to the north. He will give you an Unholy Symbol mould, which you can use to make Unholy Symbols of Zamorak. If asked, he will also bless these symbols.

Trivia

• After you have repaired the telescope talk to the Observatory assistant and he will give you a jug of wine.
• Once the player finishes the quest, they will always see with the telescope the Scorpio constellation.
• Although making the lens was meant to require a crafting level of 10, the check that is meant to stop players from making the lens doesn't properly stop execution of the script after displaying the error messages, so the lens is made anyway.
