You have to meet these requirements:

Weapon Location: In a chest at the Monster Arena to the east of the Calm Lands, after collecting at least one of each monster from the Calm Lands. Although you can find the chest before leaving the Calm Lands, you MUST have the Celestial Mirror in your inventory to open it and therefore get the weapon.

Moon Crest location: Besaid Island beach, in a chest in a cove on the east side, only accessable by swimming. You can get this very early in the game.

Moon Sigil location: Defeat all of your Aeons at Remiem Temple, then preform the Farplane Sendoff for Belgemine. All of your Aeons means ALL of them, including the secret ones like Youjimbo, Anima, and the Magus Sisters.

To get the celestial Mirror

You need to do some chocobo training with that woman in the calm lands, once you can ride a chcobo, you can get to Remiem Temple. At the Bevelle end of teh Calm lands there will be a chocobo freather to the right of the entrence. Walk over to it with your chocobo, and it will jump over to the other side, taking you to the temple, there will be a chocobo on the left hand side and a sphere with instructions, and a chocobo on the right hand side that you need to ride. You need to beat the other chocobo to the centre to get the cloudy mirror

Once you have obtained that. Take yourself back to macalania woods. There will be a woman and her kid stood at the bottom. Talk to them, learn that her husband isnt meeting them there like he should be - walk to the camp site in macalania (where you holed up near where you have that gay lake scene with Yuna and Tidus) talk to the chap there. He will go back to his wife. Follow him, talk to the couple until it emerges the KID has now gone missing

Walk up the crystal path to the centre and go left up to the dead end. the kid is there, then it will ask you if you want to use the cloudy mirror. You will now have the celestial mirror and be able to open the chest

Can't we tell I did this part last night xD

Hope that makes sense
