    Your telescope should have a rubbery black focus knob. Old 70's or 80's models came with rough-metal focusers that were all kinds of sizes, this knob is not made to fit those. If your 8-9.25" stock focus knob looks like the one in the product photo though you're good to go.
    Inside diameter: 22mm, fits +/- 2mm
    Outside diameter: 70mm
