You will need to go to the Threepio panel and become Threepio to open it up. You should be able to grab the First Blue Canister from here.

Keep following Boba Fett until you get to the one room with the really weird sculpture in it. Defeat him and go over to the left side of the room, and you will find the Second Blue Canister.

As for the next one, you will see this Artoo panel door as Boba Fett leaves. I believe there was a canister here that was obtainable through Free Play, and you should be able to get the Third Blue Canister.

As you make your way toward the Slave I, you should be able to find the Fourth Blue Canister right in the way.

When you enter into the area with the Slave I, you won’t see much of anything there. That is, until you go behind the big ship itself. Go on and see for yourself and grab the Fifth Blue Canister.

Go ahead and ride up the elevator. I believe you have to be a stormtrooper in order to use this elevator. When you get to the top, you will soon be assaulted by many, many stormtroopers. This Sixth Blue Canister is on top of the elevator, and getting it is similar to obtaining that one canister the first time this level was played, but not on the side.

Use the grappler spot to the controls, and make your way up the weird elevator. Go pass the weird conveyor until you get to a grapple spot. You should be able to get the Seventh Blue Canister from here.

Keep going until you get to the area with all the steamy smoke, go ahead and become Artoo Detoo so you can turn it off. You will find that there is a grapple point there, so use it. There isn’t much here, so feel free to hover right and go towards the screen. There is a place here that has the Eighth Blue Canister, so go and get it.

As you leave the room with all of the smoke, you will go to the hallway area towards the one room where you can extend a bridge to the Millennium Falcon. You will be able to get the Ninth Blue Canister somewhere around here.

This last one is located in an area behind the Millenium Falcon. Go ahead and go behind it and you will find the Tenth Blue Canister.
