Jeff the MAS adapter I have accepts the eyepiece thanks anyhow the problem I think is back travel, how much distance from the EP to camera CCD is required to achieve focus.

If the EP is a 20mm then the FL of the EP is 20mm so I would assume that amount of back travel (approx) is required to bring the EP to focus then the image that is projected onto the CCD should be in focus.
