A full-aperture solar filter is designed to fit over the front of a telescope. It allows safe viewing of the Sun by reducing the light by 99.99% and preventing concentrated heat from entering the telescope, which could cause injury to the user or damage to equipment.
If your telescope is not listed on our solar filter reference chart, you can determine the size of filter needed for your scope by taking the following steps:
With the three thumbscrews backed out to just inside the wall of the metal cell, place the solar filter over the outside of the telescope. It may require some light force to push the filter in place. Make sure it is seated completely over the telescope. Then lightly tighten the thumbscrews to further secure the filter on the telescope.
