Engineered Optical AlignmentProtect Eyepiece Barrels And Filters
Upgrade your stargazing setup with the Celestron 2” to 1.25” Adapter with Twist-Lock. Unlike traditional thumb-screw adapters that can scratch, gouge, or tilt your eyepieces off-axis, the internal twist-lock mechanism applies uniform centering tension around the eyepiece barrel. Crafted from durable machined black anodized aluminum with high-visibility orange anodized twist-lock rings, this adapter also features an integrated 1.25” barrel stop to protect internal diagonal mirrors from long eyepiece barrels. Threaded to accept standard 2-inch telescope filters at the base, it allows you to swap multiple 1.25” eyepieces freely while keeping a single filter securely installed.
