Hi Malcolm,

Yes, prism's position will affect the relative distance from the OAG unit where your guide camera will reach focus. If you push the prism in towards the optical axis, your guide camera will also need to follow that direction to reach focus. After all you may have to move the prism further away from the optical axis
