Great quality and value. Unfortunately, the 5 mm and the 10mm are stuck together. I tried filter wrenches to separate them, which didn't work, so I wrapped them in tape and used pipe wrenches, but that still didn’t work. I will assemble everything tomorrow that I purchased it for, and we will see if I need them separated. I also bought the Variable Extension Tube, so I hope to use it to achieve the precise length I need. Just an update SVBONY reached out to me offering a refund on this product. I was very impressed. I planned to order another set and a few other items they make because the quality and value are very good, and that gesture made me a definite SVBONY customer.

It stays loose at the end of threading. Threads perfectly on my Player One though

Hace exactamente lo que se supone que debe hacer, es un espaciador. La mayoría de las reseñas de una estrella para este producto son erróneas, ya sea por error del cliente o por desconocimiento de su uso. Esto hace exactamente lo que dice, es un espaciador, también necesitarás comprar un soporte helicoidal. y un soporte en T para su cámara que se adapta a su cámara. Vendido por la misma empresa facilita mucho las cosas. 1. El espaciador acercará el plano posterior focal, pero 2. el soporte helicoidal lo ajustará perfectamente. [La revisión que dijo que esto no funcionaría porque no es precisa solo habla de 1/3 de la solución, nuevamente ignorancia y falta de comprensión óptica.] 2. La rosca y el diámetro también son otro factor a tener en cuenta; nuevamente, las revisiones que decían que estos no se atornillarían en su adaptador no observaron correctamente dos números. a. el diámetro b. el ángulo y la resolución del hilo. Ejemplo para este producto... M42X0,75 mm si su configuración es M42x0,80, ¡no funcionará! Ambos números tienen que coincidir. Entonces, para terminar, necesitará los espaciadores, la montura helicoidal y una montura en T para su cámara, y que TODOS los elementos coincidan con el diámetro y el ángulo/resolución de la rosca. Si compras ambas piezas con el soporte en T, se venden, por lo que TODAS las tres piezas juntas FUNCIONARÁN. Si mezclas y combinas, ¡debes comprobar que TODOS los números coincidan y se alineen!

These extension tubes screw right onto the celestron T adapter that fits onto the .7 focal reducer. Nicely machined, very happy now that I've achieved 105 mm of backfocus. Great value. Also my new ZWO ASI 294 screwed right onto the T adapter. Edit...... Dont let them get stuck together, using channel locks to get them apart destroys them. Store them apart. You may find you need to paint them inside with a flat black paint. They seem to be glossy and I have had an issue with reflection. A quick spray fixed that.
