I tried to get some shots with the teleconverter on (that bought it up much closer) but the camera wouldn't 'read' the lens.
what can I do to get better shots of the craters etc? (apart from getting a bigger telescope) LOL

Hi PJs, I have the same scope and with the camera "T-Mounted" to the scope it is just a 600mm lens - as you've discovered, your 500 with a teleconverter is longer
.....
The way to get real magnification is to mount your SLR to an eyepiece...
I have a Hyperion 8mm eyepiece and an adapter ring to take the T-mount......
With this combination, I can fill the camera frame with roughly 1/6 of the moon (see attached image made up of 8 frames).....
