ASI2600MC-pro + EFW 2" + M68 OAG

I have purchased the 2600 and have been using it for some time. Recently I decided to add the EFW2" and the M68 OAG since the backspace distance and camera size is the same as the 6200 cameras. Everything is connected and working perfect, but I cannot get the Guide camera to focus. I need more in travel , but the camera cannot go any further into the OAG. I moved the prism closer to the camera to keep it out of the main camera sensor area. Do I need to try something else go get focus? Everything connects how it was designed, so I am surprised I cannot reach focus on the guide camera.

1.Try to move the prism more close to the guide camera.
2.Try to adjust the helical focuser.

I don't seem to have enough in-travel. I'm using the 174 mini guide camera and it's all the way in the OAG as far as it can go, and the helical focuser is turned to 0 which is all the way in, and I can't quite reach focus. So the only option is to move the prism now. I just don't know which direction to move the prism. Either closer to the guide camera, or closer to the center of the field of view. I'll start with moving it closer to the camera.

Could you send us pictures to show us how did you connect the adapter?
Is there any possibilty that you can change the palce of the OAG?
