This Full Aperture Glass Solar Filter fits telescopes, finders and other optics with an outside diameter between 14 7/8” (378mm) and 15 1/8” (384mm). (Includes Orion 12.5"; 12” Dobs Zhumell)
These are safe full aperture (sometimes referred as clear aperture) solar filters. Glass Full Aperture Solar Filters, compared to Off-Axis Solar Filters, allow substantially more light into the optics because the aperture size is close to the aperture size of the telescope or binocular. Glass Full Aperture Solar Filters are for visual observing or imaging and allow the best possible daytime viewing when there is minimal atmospheric turbulence (but remember that there is often atmospheric turbulence). If turbulence is present, a mask can be put over the end of the filter to effectively reduce the aperture. In effect, you can easily mimic an Off-Axis Solar Filter.
This premium solar filter has an aluminum cell that is secured and centered to the tube end of the telescope with nylon thumb screws and felt padding. The clear aperture is made with high quality hand selected and inspected reflective coated glass. This is the highest quality, durable, glass, full aperture solar filter on the market. The sun is viewed in a natural yellowish-orange image. The filter can be used for direct viewing through the telescope or for photography.
The filter box is foam lined for protection and shock absorption during handling. It is durable enough to store the filter while not in use.
