Great Focuser

Good build quality...it is a helical focuser so no surprise that whatever is attached to it rotates, Using it to attach an asi224 to the Orion Multiuse Finderscope (with some additional T2 spacers) for guiding. Movement is smooth, so simply loosen the thumbscrews for the camera and rotate until focused....re-tighten the screws. Works like a charm

Happy with Baader 1.25 T2 Adapter

The adapter met all expectations. Actually, I made two adapters out of acetyl round stock that worked pretty well. One problem I didn't anticipate was that the coefficient of expansion for acetyl was much greater than metal, so eyepiece was trapped by the acetyl when the weather got very cold. The Baader adapter has excellent features for focusing and also distributes the screw clamp pressure uniformly around the circumference of the eyepiece, etc.. I liked it so much I bought two of them.

It's a good product but....

The piece is well made and looks good. It is a good product. howeverI have to agree 100% with DesertSky on his review. Depending on what you are doing with this the rotation could cause you substantial problems. The other problem I encountered was the viscosity of the grease on the threads. I was hoping to use this for fine tuning the focus on a SCT on very high magnifications. It proved to be so stiff I might as well been adjusting the primary mirror. I did try to flush out whatever was in there and replace it with a very fine Teflon grease. Works better now.. I would recommend it with the for mentioned qualifiers.

Nicely made but be aware

When you focus this item, the 1.25" tube turns which is fine with an eyepiece but if you are using a camera you can't focus and maintain alignment of the chip.
