Abstract
In a reflecting telescope, a diagonal mirror is supported by a spider comprising four thin flexible metal vanes secured to a mirror carrier by axially slotted pins which are rotatable for adjusting vane tension. These vanes provide an extremely stable mirror support, which exhibits low obscuration and minimizes the effect of diffraction spikes.
