ASI071MC Camera and Esprit 120

Hi guys, I have the above equipment that I had some time to play with over the weekend. I had an issue whereby I couldn't get the camera to focus at all. I tried with and without the diagonal, threw in a barlow, nothing. The camera was definitely working as it would blow out when you wave a light in front of the scope.

I noted this morning that the camera has a back focus of 17.5mm, and the scope 75mm. Dumb question, but he scope back focus means 0-75mm right? This means it should focus pretty much with the focuser most of the way in?

Anyway, thanks in advance for any clues you may be able to provide.
