You want to get the eyepiece lens as close to the camera lens as you
possibly can. I had our machine shop make me a very thin nylon washer, with
an OD just right to fit in the camera threads, and an ID a little larger
than the size of the transparent part of the camera lens barrier. Even so,
I have to zoom most of the way in to hide the circular field edge of the
eyepiece.

You could probably do the same with milk jug plastic. Or a piece of
paper.
