Svbony M48/M48 variable extension tube (24-35 mm)

The Svbony SV109 M48/M48 Adjustable Extension Extension Arm (24-35 mm) is designed for astrophotography use. The M48 extension pieces function as a spacer ring to adjust the camera to the right distance behind, for example, the corrector of a telescope.

The adjustable M48 extension piece can also be used separately, because the thread of the folding part is also M48.
