Orion Full Aperture Solar Filter with 12.13 inch Int Dia

The Orion Full Aperture Solar Filter with 12.13 inch Internal Diameter is a superb full-aperture optical glass filter that delivers you views of the Solar surface, without risk to the internal workings of your telescope - or your eyes! Superior to Mylar filtering, the Orion Solar Filters provide a natural yellow/orange image of the Sun, Sunspots and surface granulation. This filter also provides superior results when imaging.

A scratch-resistant surface is provided by a hard-wearing, machine-polished glass and an advanced, triple-coated nickel-chromium stainless steel alloy passes a tiny percentage of safe Solar emission wavelengths - providing full protection from dangerous infrared and ultraviolet radiation. The Orion filters sit in an aluminium cell, which neatly fits over the front of your telescope, and can be further secured by three 120-degree mounting bolts and packed to a precise fit with included foam tape.
