I am going to try a few imaging sessions to see if there is a real problem. Then my next step would be a regressing if needed. Thanks for the tip on the high friction clutch pads. Will surely keep

I don't understand how you came up with this.? Regardless of optical resolution or camera seconds per pixel image scale or how well the mount tracks the rate limiting factor when imaging from the

The amount of counterweight should not make a difference.? The most counterweight I have used was:? 3x21 + 1x11 + 1x7 = 81 pounds total CW.? But even my typical 70 pounds of CW shows no slippage
