Product Overview
- Ideal for Newton Focuser e.g. Baader Newton Crayford focusers with only 1mm optical path length
- Provides three separate mounting options for 1¼" accessories
- Side clamping screw and brass clamping ring for secure grip. Also includes countersunk grub screws for permanent or quick release operation of the brass clamping ring.
- The countersunk Delrin grub screws allow for the pressure to be set correctly. This acts as a quick release without relying on set screws. When an eye piece is inserted it is held securely and safely while still allowing the eye piece to be removed.
Our 2"/1¼” reducer permits you convert your 2" focuser for use with 1¼” 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, 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.
