The SVBONY helical focuser allows for precise adjustment of eyepieces or cameras. It is ideal in combination with a guide scope and a guiding camera, such as the SV165 mini guide scope series.
During the focus adjustment, the attached accessories maintain their orientation and do not rotate. The exact focus position can be fixed with a locking nut.
