These full aperture thin film are safe solar filters that permit the most possible light through the telescope which allows your telescope’s full aperture to be viewed. The daytime viewing is at its best with the full aperture when the atmosphere is least turbulent. Made from .002” thick black poly plastic, the optical thin film is durable and with proper care and normal use, can last for many years. Just as the off axis solar filter and full aperture glass solar filters, there is an aluminum cell securely attached to the telescope’s tube end by a nylon thumb screw. Made from high quality, the clear aperture is stock with optical thin film that has been thoroughly inspected. This is a durable, high quality, thin film solar filter that you’ll find anywhere on the market. It provides a natural yellowish-orange image when viewing and can also be used for viewing directly through the telescope and/or for photography.
This filter comes packaged in a foam-lined box that is placed in plastic which absorbs any possible rough handling and shock during shipping. The box is also great for storing your filter when you aren’t using it. By following the instructions provided with the unit for care and use, you will have many years of use with this product.
