Some early versions of this design have very little clearance between the factory dust cover and the secondary housing. To make room for the knobs, we offer a free set of spacers that attach to the ring around the corrector plate to move the dust cover slightly away from the secondary assembly. These spacers are not needed for later versions of this telescope.
