SVBONY SV119 Extension Tube Kit for Cameras and eyepieces 5mm 10mm 15mm 30mm M48x0.75 on Both Sides for Solving Spacing Problems in Astrophotography

Well they did it again . Great set of spacers at a great price . Threads are clean paint is nice . Good selection of different sizes and let’s face it ……. We all need them so save some money and buy a great set for less than the overpriced guys

These seem to be better quality than some others I have ordered and are less sensitive to the threads locking up when tightened. Happy with the purchase.

As with all SVBony products I’ve purchased, great quality, especially for the price!

I received the Extension Tube Kit the very next day of ordering. Unfortunately, I ordered the wrong size M48x0.75. I have since reordered the correct size M42x0.75, and have received it. I am very pleased with the extensions. I returned the incorrect item.

I have bought several tubes, several extensions and focal reductors from svbony, and they really deliver good products and great prices. The only thing is that sometimes the roundness of the tubes is not perfect, that you will notice when trying to couple or insert them with the focuser or the 1.25" openings. It seems they are a tiny fraction of the roundness of their pieces off.

It seems like a nice set of extensions, but the insides need to be flat black, not shiny or reflective.

Solid workmanship. Threads and tubing are great. The only area of improvement would be to label the spacer's size on each ring.

Svbony wasn’t the only brand available to buy, but my decision to go with their rings was based on previous experience with them. And I was not disappointed! It fitted perfectly with my flattener and camera, which are from different brand. Beautiful construction with anti-reflection internal surfaces! I totally recommend Svbony rings, no doubt!
