How do you get to the insomniac museum in ratchet and clank 3?

first you must change your playstation hour to 3:00 - 4:00 am.then you must go to the teleporter at metropolis city and press the triangle button. However after you go through the first room go left, jump up the ledge, then run and jump over a nother ledge(If you dont' you will fall.) There should be another room. Go left up the ledge and there should be a teleporter saying 'Insomaniac Muesum' Also, you can find all the trophies and go to the trophy room on the Starship Pheonix. there is a door that normally doesn't open but it should take you to the museum. some trophies are completing all Annihlation Nation challenges, completing all Galatic Rangers challenges, getting your nanotech to 200(the max) and getting omega level for all your weapons. You should have the Map-O-Matic so it can help you find trophies on normal planets. (Some are on Florana, Koros and the Command center)
