Hey thanks for the information it helps answer many of my observations and experiences.
The camera I am using is a Nikon D3200 for the lens projection I set the camera to manual and remove the lens (of course).
Then I attach the camera behind the eyepiece. I have found the 13mm Plossl works quite well at a variety of projection lengths. Though I try to keep the projection length as short as possible to save the light drop off. It gets dim real quick at longer projection/s. I have tinkered with a 6mm nagler and it also seems to work quite well.
Hmmm it seems the longer I go with the eyepiece the more problems I have. It seems to be to do with the eye relief distance.
I have decided to get myself a CCD camera in the near future (much easier to use). This afocal has at least taught me a bit about my optics.
