It work if i use my 2x.barlow though it works.
Am i doing something wrong?
You are not doing anything wrong, your setup simply does not have enough back focus to use the eyepiece projection adapter in the optical train you've configured. The 2x barlow you tried is likely one with a lense mounted at the front of the assembly, much like my 3x Televue, allowing it to extend the light cone through the optical arrangement you configured. I have an old 80mm Lumicon finder I use in a similar fashion. I can't use a diagonal with it for the same reason.
Since you did not give us any other details regarding the scope or the various piece parts in optical arrangement you are attempting to configure it is difficult to know what to suggest at this point. Let us know if you still need assistance.
There is only one constant in our infinite universe; it is change.
