Hi Alex
Thanks for your advice. The problem is I have tried to put more weight on the mirror box, this fixed the problem of the scope falling to horizon, but it didn’t fix it pointing to the sky by itself. It moved both ways on its own when I get to a certain degree. Even without the extra weight it still falls both ways up and down I mean I would rather it go up on its own than down. But still very annoying. You mentioned about the bearings being centre of gravity. I’m guessing they are not in the correct spot, the bearings don’t sit centre of the mirror box, they are about 20mm more to the front of the mirror box. But the truss clamps I made don’t allow me to bring the bearings back 20mm. Would the bearing position be the problem here? Counter weights only work for the scope not dropping to horizon, but adding more weight to the mirror box brings the scope up faster by itself. So when I have the scope at about 85 degrees it will move on its own to vertical with or without the weights. I’m thinking I might need to make new bearings so I can move them to the centre of the mirror box. I really am having a hard time trying to balance this. I did try a elastic bungie cord, one that stretches very easily and it worked pretty well for keeping the scope from falling, but I still have the problem of it raising in its own when at about 85 degrees. Anyway I hope this all makes sense, and thanks heaps for your advice.
