Baader 1-1/4" to 2" ClickLock Expansion Adapter

This 1.25" to 2" Expansion Adapter from Baader enables you to use of 2" eyepieces in 1.25" focusers and diagonals. The nosepiece is threaded for 1.25" filters, and the internal surfaces are fully blackened to control stray light reflections.

The Baader ClickLock Expansion Adapter's modular construction permits other uses. The 1.25" nosepiece may be removed to expose an internal T-2 photo thread, enabling connection to a wide variety of Baader Astro T-2 accessories. Also, the T-2 threaded ring may be removed to expose a 2" SCT thread. The optical path length is 49mm.

Please Note: Using 2" eyepieces in a 1.25" focuser will always result in some vignetting of the image due to the narrowing of the barrel size.

Customer Reviews (4.6 / 5 · 5 reviews)

Avery ★★★★★

The ClickLock mechanism locks my 2" eyepieces firmly with a satisfying click, and the threaded nosepiece screwed into my diagonal without any wobble. Took about a minute to swap it in and now the whole setup feels more solid than the old thumbscrew adapter.

Elizabeth ★★★★★

Finally, my 1.25” diagonal can hold a 2” eyepiece without wobble — the threaded nosepiece screws in cleanly and the ClickLock collar snaps shut with a reassuring click, no adapter slippage mid-session. It’s a bit of a squeeze to twist if your fingers are cold, but once locked, it’s rock solid.

Joseph Q. ★★★★★

Finally, a solid adapter that lets me use my larger 2" eyepieces in my existing 1.25" focuser. The ClickLock mechanism grips the barrel securely without any wobble.
