Just looking at the setup - with the guidescope on one side of the scope and no corresponding counterweight on the other it must give you a few balance problems at times?
Edit: Actually looking more closely I can see that you have offset the saddle to one side so the lateral balance is not an issue!

Hi Dave
I'm getting there...
I use an Orion ED80 refractor and SXV-H9 guide camera.
The ProLine and CFW-5-7 and corrector weigh a bit too
Yes the OTA is off set and so is the camera a bit (rotated about 10deg), I moved the guide scope forward too so it would be held more centrally and rigidly and doing this meant the scope became front heavy (can't move the scope back in the cradle anymore or the CFW will hit the NJP head) so I had to velcro and tape some weights to the back of the mirror cell back plate so this meant more counter weights...
I just want some good seeing
Mike
