Telescope Collimation Tools

Collimation is the process of aligning a telescope's mirrors or lenses so they share one optical axis; even a small misalignment softens stars and planetary detail, and fast Newtonians and Dobsonians need checking most often. Laser collimators such as the Farpoint 650nm and Baader Laser-Colli MkIII give a quick check in daylight or the field, Cheshire eyepieces and sight tubes like Takahashi's collimating eyepiece and crosshair tube give a precise visual reference, and Bob's Knobs replace SCT and Newtonian collimation screws with hand-turnable knobs. For sensor tilt in an imaging train, see the William Optics Image Plane Tilt Adjuster, and if you're unsure which tool fits your focuser or mirror cell, ask us before you order.
