Every reflector owner knows the ritual: a Cheshire collimation cap in the focuser, one eye squinting down the tube, nudging the mirror screws until the optics line up perfectly. Collimation is half maintenance, half meditation — and the Cheshire is the trusty tool that makes the misalignment visible. This edition is for Newtonian and Dobsonian owners who find a strange peace in squaring up their optics before a clear night. A premium tee for the telescope tinkerer who collimates as therapy. Available in 7 sizes (S–4XL) and 10 colorways.
