But what are the straps going below the deck for? A counterweight?

Andy, I sure do have that 12". Don't use it as much due to increasing disabilities. I've even shrunk 2.5" in height, but the telescope didn't. I have a telescope that gets far more usage.

I have something similar in my head but my counter weight hangs and uses the rocker box as a rail to glide on.

Quote:Unfortunately this counterweight device won't work well because as the tube rotates from vertical to horizontal, the amount of torque around the altitude axis increases greatly.
Quote: But I think the simplest way to build a Newtonian that is balanced around the eyepiece is to just use a counterweight at the opposite end from the mirror.
