Texts and list members suggest the scope focus mechanism can be adjusted for near- or far-sighted problems, but some form of vision correction if called for with an astigmatism. If the distortion is not corrected with eyeglasses or contacts, how will this affect natural horizon observations, lunars or IE checks?
