Are you saying the distance between the 2 X lens and the eyepiece is of importance here?

It appears that you are attempting eyepiece projection onto the film. What still is not clear is the location of your eyepiece-Barlow combination. Is it inside the Camera Adapter tube? If so, it looks as if it will be too far back from the telescope mirror's focal point to have any chance of coming to a focus.
The spacing between the Barlow lens and the eyepiece is important. In normal visual operation, the field stop of the eyepiece will be approximately abreast of the locking screw on the back end of the Barlow tube, and the Barlow lens will be a little over two inches in front of the stop. If you screw the Barlow lens directly into the eyepiece the spacing will be much less, reducing the multiplication and upsetting the optical correction.
