TS-Optics 2 inch (M48) Extension Tube with Double Sided 2-inch Filter Thread - 10mm Length
An important addition to our range of focal extensions, mainly because the need for larger free aperture in comparison to the widely used M42 (T-threaded) versions. The Extension Tube has to be screwed into the Filter thread from a 2" eyepiece or a 2" adaptation and therefore will extend the barrel by 10mm.
On the telescope side you are able to adapt a Filterthread or even a further Extension Tube. So you are able to extend the barrel user defined without reducing the fitting accuracy like using barrels which are wobbling.

- Black anodized
