Hi Russell,
Your problem is achieving focus. There may well be issues with collimation, but they are not important right now.
With many reflectors, it's not possible to get focus on to the sensor of your camera with the standard amount of travel allowed by your focus mechanism. The chip in your camera sits too far back.
The solution is to get your camera closer to the primary mirror. As has been suggested above, see if you can do without the adapter. I made mine work by getting some long screws that hold the camera in place directly in the T-ring. Very dodgy, but it works!
Alternatively, you may have to move the primary mirror up the tube a bit (1-2 cm). This sounds scary but with some scopes can just be a matter of replacing the bolts that hold the primary mirror in place with some longer bolts - just $3 at Bunnings.
There are lots of threads on this on the forum, if you search for "Newtonian camera focus" or similar.
