Looking cool was an unintended side effect. I moved the guidescope so that it mounts on the main scope dovetail to lower the CG. When I tired it on top, I had to add another rail and the CG moved so far out that I had to slide the counterweights to the outer limit. The resonant frequency got so low and I was very concerned about vibration. By moving the Vixen to the bottom, I could get rid of the second rail and pull the counterweights way up and things got really tight. It's on the centerline so everything is easy to balance. Frankly, Meade got it right by mounting their guidescope and finder really low, near the mount dovetail. One of these days, I intend to machine a plate that will allow mounting my other (heavy) Stellarview 80 mm finder next to the main scope with room for another scope or counterweight on the opposite side--similar to what Meade does. As a rule of thumb, you will always have a more stable mount if you can keep the distribution of mass as close as possible to the CG position.

It was what I always thought about building, but I bought it from fellow CN member Ron Price. As I recall, Ron was a mechanical engineer on the LBT program and he gets all the credit for designing and building it. It is a superb design and unbelievably stable. It is hell-for-stout and I would guess that it could easily handle a scope up to about 18".
That is one heck of a rolling pier! Wow.
