Description
This robust all-metal 1.25-inch extension tube will fit in a standard 1.25-inch telescope drawtube and will accept 1.25-inch eyepieces and other 1.25-inch accessories.
It is sometimes used to achieve focusing with long focal length eyepieces where focal travel on the telescope is limited. This can sometimes happen with Newtonians and some refractors that have been designed specifically for binoviewer use. This adapter is 50mm long and will extend the length of the drawtube by 28mm. It has a brass compression ring and it is threaded for 1.25-inch filters.
