Collimation problem on a LB16

Hi !
First of all, sorry for my english !
I'm using the catseye collimation tools on my lightbridge 16".
I follow all the steps (center the secondary under the focuser, center the primary in the secondary, then center the primary). My focuser is, as well, well centered in the tube
The problem comes when i use the auto-collimator. When i look into it, i see the dark zone i'm suppose to, but when i do the adjustement to get all the triangles together, my secondary goes in that position :

Everything is well centered but it seems that i loose some light here 
Any ideas ?
Thx a lot !
Renaud
