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.  |
The problem with using a longer dovetail as Katl has suggested it that you can get flex in the dovetail and to where it joins. You'd be effectively canterlevering the scope. Although it will solve one problem, it may introduce another. I'm not sure what the weight of your entire setup is but if you have room for extra weight, you could mount a weight on the front tube ring. Again not knowing your exact setup, I can't say where but on my tube rings I have dovetail fixings on both sides of the rings. You could add a weight on the opposite side that your dovetail mounts to on the front ring.
