I have a class project where I am using several servos to control a telescope. I'm trying to figure out the torque needed to rotate the tilt of the telescope with a servo from 0 to 90 degrees. I haven't come across any similar problems online that have examples. I know that the one I am currently using is close, but just isn't enough to lift the telescope up by itself.
From the experiments I've done, I've been able to rotate a ~6oz object almost perfectly, but the ~12oz telescope is too much. I assume that if I get the 133oz-in servo, it will be able to rotate 2.6 times the mass or 15.6oz in this case.
Here is a modified diagram of the original setup. The circular disc on the servo tip is 1" in diameter.
And here is what it looks like assembled (without telescope attached yet).
