First, take your Newt outside during the day, remove any eyepiece;
remove the lens from the camera, and hold the camera up a few centimetres from the focuser tube, rack the focuser fully in toward
the tube and move the camera closer and closer to the open end of the focuser tube. If the lens mounting face of the camera comes
into contact with the focuser tube and the camera has not reached focus, then the scope is not designed for imaging. If it is obvious that it has nearly reached focus you might be able to fit longer collimation screws to the primary mirror, and achieve focus. If it is still quite a way from focus you would need to move the primary mirror further up inside the tube.
If you can reach focus with the camera at least 10mm from the focuser
all you need is the appropriate T-ring for your camera and your'e off and running.
