10mm 길이 48mm 연장 튜브 (SFE-M48-010)

I needed a small spacer for my focuser, and this 10mm tube fits perfectly with its 2.0-inch outside diameter. The threads are smooth and engage nicely, making adjustments a breeze. Works great for getting that precise back focus.

The threads on this 10mm extension tube are precisely cut—the female end threaded smoothly onto my filter wheel without any wobble. It adds just the right spacing for my new camera setup to reach focus.

Finally got this extension tube to dial in the back focus on my ZWO camera setup. The 10mm length was exactly what I needed to get sharp stars across the whole frame. The threads are smooth and consistent, which makes a big difference when you're swapping gear in the dark.
