T2 Female to 1.25" Male Thread (M28.5x0.6) Reducer for Newtonian Telescope Laser Collimator

This custom-designed adapter is specifically made for use with the Hotech SCA laser collimator and my 2"-to-1.25" reducer with a removable top. When the top is removed, it reveals a T2 male thread, which is slightly oversized by 0.5mm to ensure a precise and snug fit in your focuser through a threaded connection. This setup allows for perfect collimation results, especially when working with large sensors.

Printed in durable Carbon PETG, the adapter is a reliable addition to your collimation setup. It has been tested and worked great for me.

P.S.: I’ve also uploaded the Fusion 360 file, allowing you to adjust the threads or dimensions as needed.
