Seems very cool but all of the photos and videos I could find is about how to build it not the most important thing.. how good it is as an actual telescope how does the moon/stars etc look though it
The mechanical part can influence the view via "tube currents" (air flowing in the optical path due to heat convection) or by not allowing good heat flow to and from the mirror so it stabilizes quickly.
There's a few more things to consider, but remember it's mostly the optics.
I don't know much about telescopes :p
