    Excellent Product

    The beautiful design & quality construction of this diagonal is what you both expect & get from a William Optics product. When you pick it up you know that it is an all metal & glass construction with nothing in it made of plastic. It goes perfectly with my William Optics Zenithstar 61 telescope & holds my 2” William Optics 25mm eyepiece with precision.

    Willaim Optics Dura Bright 2" diagonal

    Required an adaptor to install in my Meade LX90. Easy installation using the adaptor even in the dark. Lets the maximum amount of light come through the optical path. Be aware that you will need to reset the LX90 Max. Elevation since the size of the diagonal with a 2" or wide FOV 1 1/4" eyepiece limits the elevation in auto slew and tracking modes.
