Adapter from helical focuser to 1.25 inch
Description
An adapter to fit the SVBony helical focuser to a 1.25 inch barrel. The helical focuser has a M31 x 0.5 male thread. My adapter screws onto the focuser (M31 x 0.5 thread) and provides a 1.25 inch barrel. It includes a M28 x 0.6 filter thread on the telescope side as well :-)
