with a system like this you only tighten one nut to put the whole system into tension. this might look big and heavy but this telescope was made with thin alum. and light rollers. this only wieghed 15 lbs just the telescope part


I will say we have something even better than this.

Do you have any more pictures or diagrams? My team is trying something similar this year, and any information would be helpful. Some of the doubters are still not quite seeing how the arm would work, and any concrete evidence would be useful.
