Metal 0.965 inches to 1.25 inches Telescope Eyepiece Adapter Description A precisionmade adapter that lets you use standard 1.25 inches eyepieces with telescopes that accept a 0.965 inches barrel. Constructed from aluminum alloy for a lightweight, durable connection that keeps optical alignment and minimizes play between eyepiece and focuser. Key benefits Solve compatibility issues: adapts older or compact telescope focusers with a 0.965 inches outer diameter to accept modern 1.25 inches eyepieces. Durable and lightweight: aluminum alloy construction resists corrosion and keeps weight low for portable setups. Secure fit and stable performance: machined dimensions provide a snug connection to reduce wobble and maintain consistent alignment while observing. Easy to use: simple slipin installation requires no tools for most setups, making eyepiece swapping quick in the field. Important attributes Material: aluminum alloy Telescope interface outer diameter: 0.965 inches (24.5 mm) Eyepiece interface inner diameter: 1.25 inches (31.7 mm) Package includes: 1 x metal 0.965 inches to 1.25 inches telescope eyepiece adapter Compatibility and function Designed to convert a 0.965 inches focuser or barrel to accept 1.25 inches eyepieces and accessories. Works with standard 1.25 inches eyepieces, filters, and other 1.25 inches telescope accessories. Ideal for older telescopes that use the 0.965 inches standard and for users who want to use modern eyepieces without modifying the focuser. Typical use scenarios Vintage telescope upgrade: or extend the eyepiece options on a classic scope that uses a 0.965 inches barrel so you can use a wider selection of modern 1.25 inches eyepieces. Field observing and outreach: Quickly adapt a small refractor or tabletop telescope to accept common 1.25 inches eyepieces during star parties or educational sessions. Accessory compatibility: Use 1.25 inches filters or Barlow lenses on instruments with a 0.965 inches interface when you need specific optical accessories. Installation and care Slide the adapter into the telescope focuser or barrel with light pressure until snug. Insert the 1.25 inches eyepiece and secure if your focuser uses a thumbscrew. Clean with a soft, dry cloth. Avoid harsh chemicals that can damage the finish. Store in a dry place when not in use. This adapter provides a straightforward, reliable way to bridge two common eyepiece standards, extending the usability of telescopes and simplifying accessory sharing.
