But how about tolerance to wind?? ?I have been trying to use my 127mm refractor at f7.5 or f5.3 (with the reducer) and having difficulty even with a mild breeze.? ?
With lighter winds, I'd check the inertia being placed about the DEC axis and minimize that.? A 5-inch refractor can increase the inertia significantly about the declination axis.? Dampening a large radius balance wheel (pendulum) structure that can apply torque forces down to the tripod can easily become an issue.? The DEC may not track much, but it can wind up if buffeted.
