Balancing is fairly straightfoward with the side by side from StarStuff. The mount has three 5.4kg and two 4.?kg counterweights to balance this lot. Plus a smaller one wired on. I moved the OTA back in its rings to almost balance the fridge. The images below show it better.

My mount has also has belt drives with very robust stepper motors which means it can handle far more than a standard gearbox equipped mount. I once had the SN10, 100ED and 150mm achro all on at once and it tracked fine.

There is also a 15s exposure of M42 with a crop showing Trapezium detail.. Shows how steady everything is even with two fans spinning on the fridge.
