Offner relay optics added to large spaceborne telescope design to provide improved capability for fine pointing. Performs telescope fine pointing by tilting relatively small relay secondary mirror, instead of pointing entire telescope. Reimaged pupil within relay also allows for cost-effective stray-light control.
