The GPC1.25x will move the focal point outward between 15 and 30mm depending on where it is placed in the optical train. Remember that the cemented lens element needs to be flipped over if you’re putting it into the front of the diagonal.
If you have the 2” nosepiece you can insert the GPC into the nosepiece using the little black ring spacer.
Convex side of the GPC optic faces toward telescope objective…
