The Baader 2"/1.25" reducer permits you to convert your 2" focuser for use with 1.25" eyepieces and accessories. As with its little brother, the 2" reducer incorporates several useful features. A captive spring bronze lock ring guarantees protection of your eyepiece barrels from damage. This reducer also incorporates two large nickel-plated brass knurled clamp screws that are oriented 90 degrees apart. The inclusion of two clamp screws results in a superior 3-point attachment that completely constrains your equipment from wobble, which is particularly important for imaging applications (typical single clamp screw adapters still allow some motion). Also, for those users that are physically unable to firmly grasp and tighten lock screws, the addition of a second screw doubles the locking force (ie, particularly nice for those unable to grip tightly due to arthritis).

The input side is provided with 48mm filter threads and also includes a nested internal T-2 thread which enables you to use the reducer along with the other T-2 system components. One more unique feature sets our reducer apart it includes an external T-2 thread that surrounds the eyepiece opening (covered and dressed by a knurled removable ring). This thread permits you to couple other T-2 accessories to the output side. In one application, you can attach T-2 Extension Tubes and create an extremely rigid afocal or eyepiece projection system. Once again, you are free to creatively construct your own combinations.

George ★★★★★

Swapping between my 2-inch and 1.25-inch eyepieces is now effortless with this reducer; the threads are precise and it fits securely in my focuser without any wobble. It's a simple adapter that does exactly what it should, and it's built solidly enough that I don't worry about it loosening during lo

Zoe ★★★★★

The brass compression ring holds my 1.25" eyepieces snugly with no wobble at all. Such a clean, simple solution for switching between the two sizes.

Sebastian ★★★★★

It saved me from having to swap out the entire focuser when I switch between 2" and 1.25" eyepieces, and it threads on smoothly without any wobble.
