Abstract
Means for centering a reticle on the optical axis of a telescope comprises, within the telescope body, a split collar tapped to accommodate two pairs of diametrically opposed adjustment screws which bear upon rectilinear surfaces of a centrally located reticle mount. The arrangement provides a dust-proof seal for the telescope interior and ensures against stresses tending toward reticle misalignment.
