Hi Dave,
Yes, the C14 is quite heavy for the DDM60. But I did manage to trim down, replacing the heavy STL with a FLI ML and getting rid of my rotator.
But the wind is still a factor with the large wind area of the OTA and quite a bit of flexure in my pier. Adding on the dome has also helped. I'm not sure if a solid tripod as you will be using will eliminate the flexure caused by wind. In theory, the DDM with motor drive and sensitive encoders should respond well and counteract the effects of?wind gusts.
