Sometimes you cannot get to the right focal plane for focusing with a camera or eyepiece. This extension tube kit solves this problem. You can use this extender with any camera or eyepiece or with various adapters. The M48*0.75 threads on both ends make it extremely versatile. Use this extender for obtaining the correct image scale or for the exact spacing required for a reducer or field flattener. You can reach the extension length required by combining several extenders of different lengths.

This tube is precisely machined out of good quality materials. My 2 inch (actually, 48mm) Optolong filters screw into it just as they should, no snags or rough spots. And it joins up with the focuser or a reducer with a few twists, no problem. Recommended.

I ordered the 10mm M48 extension tube which has the size marked upon the side for handy reference. The tube is well machined and combined with my other M48 tubes with no issues. The threads are smooth with no binding. These are good value and quality M48 extension tubes.
