Victoria B. ★★★★★

The M42 thread pitch matched my other T-thread parts perfectly, so screwing this in was smooth with no wobble or cross-threading. I added it between my camera and field flattener, and the extra 26mm made a small but noticeable difference in corner star sharpness. Solid, straightforward spacer for di

Finally got the spacing dialed in for my coma corrector with this 26mm tube, and the M42 threads held the camera perfectly square to the scope. The extra length made all the difference in star shape at the corners, and it’s solid enough that I don’t worry about flexure during long exposures.

Scarlett M. ★★★★★

The M42 threads engaged smoothly right from the start, no binding or cross-threading issues at all. This 26mm tube gave me exactly the spacing I needed to get sharp stars across the whole frame.
