Bahtinov mask is a go!

Another problem I'm having is balancing the scope on the mount.
With the .85 reducer/flatener, 55 mm spacer between the reducer and the camera and the largish 294mc camera, then wind the focuser out a bit for focus, the balance is always biased towards the camera. I have pushed the OTA as far forward as I can in the rings and have slid the dovetail as far forward as I can till it hits the allen key bolts and I have run out of adjustment.
Is this normal or something to be concerned about? I understand that an unbalanced scope will add extra strain and wear on the gears etc and can also throw out tracking.
Thanks again.
