Interesting design, can you change the focal length by tightening/loosening the wingnut? If so it makes a nice way of being able to reduce the heat easily without moving the dish.
yes we can, actually it did not work at the begining, then I tighten the screw so it can start the fire (need to be careful not to break plastic mirror)
