The Svbony SV109 T2/T2 adjustable extension arm (24-35 mm) is designed for astrophotography use. The T2 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 T2 extension piece can also be used separately, because the thread of the threaded part is also T2 (M42x0.75).
