Tools for lining up a telescope's optics — laser collimators for fast Newtonians and Dobsonians, Cheshire eyepieces and crosshair sight tubes for optical alignment, and replacement collimation knobs and springs for SCTs, Maksutovs and Newtonians.
Goods ship factory-sealed; we don't collimate or adjust anything before despatch. If you're not sure which tool suits your focuser or mirror cell, ask us before you order and we'll confirm the fit.
