Here are a couple of pictures as requested (so sorry for the image sizes, I couldn't find a way to reduce them?)

So the images show the assembly attached to the back of the scope and an "exploded" view of the components.
When I look through the prism with no eyepiece during the day, I can see the image of my garden very clearly.
When I look through the eyepiece alone, with about 150mm of eye relief I can see clearly.
When I combine the two with about 150mm of eye relief I can see clearly, I just cannot get an image to form when my eye is at a more reasonable distance when focusing via the scope, which may indicate that the focus mechanism on the scope is broken, but it doesn;t seem to be?
I'm sure this will lead someone to an "AH HA" moment and tell me how daft I'm being and that all I need to do is.....
Over to you
