With its 1.25'' barrel diameter, this eyepiece can still be used with a 2'' focuser with a special adapter. Therefore, this eyepiece can be used with a telescope of any brand and make. For even more comfortable observations, this eyepiece is fitted with a twist-up rubber eyecup. The eyepiece shell is made of lightweight aluminum.
