Best Collimators for Razor-Sharp Optics (2026)
As an Amazon Associate I earn from qualifying purchases.
Collimation aligns your telescope's mirrors so stars focus to tight points, and the right tool depends on your scope. Laser collimators are fast and work in the dark but need to be well collimated themselves to be trusted. Cheshire eyepieces and sight tubes use daylight and never drift, making them a reliable reference. Check that the tool fits your focuser barrel size and suits your design, since Newtonians, SCTs, and refractors each have different alignment needs. Collimators suit owners of Newtonian reflectors, which drift out of alignment with handling and transport, and anyone chasing the last bit of planetary sharpness. A practical tip: a Cheshire and a laser complement each other well. Use the Cheshire to set the secondary mirror accurately, then the laser for quick primary tweaks at the eyepiece before an observing session, and finish with a star test to confirm the result.
