A reflector is only as sharp as its mirror alignment. Stars bloating into comets? Collimation. Soft planetary detail? Collimation. This Mirror Alignment edition honors the patient art of squaring up primary and secondary mirrors until the optics snap into focus — the difference between a frustrating night and a flawless one. For Newtonian and Dob owners who know that great views start with aligned glass. A premium telescope tee for the collimation-obsessed. Available in 7 sizes (S–4XL) and 10 colorways.
