[David Fitz-Henr]

I have completed the tube counterweight assembly that will be used on the scope to provide fine balance when changing camera / eyepiece, etc. It is based on a similar principle to my 8" prototype, whereby you can slide the counterweight along the axis of the tube, but also slide the whole assembly around the tube circumference (max 120 degrees) to provide lateral balance (eg. if the guidescope, finderscope, RigRunner, etc results in excess weight on one side of the tube). To facilitate rotating the whole assembly around 120 degrees of the tube circumference I have added a clutch on each end (a small teflon "washer" that I turned that is tensioned against the CF rail via a grub screw) - this prevents the whole thing acidentally flopping when the lock screws ( two at each end) are released. Anyway, see attached pictures to get an idea of what I am talking about.
