Adjustable Solar Filter to adapt lenses and telescopes for safely viewing the sun in its natural yellow color. Certified for safe direct solar viewing, the filter blocks greater than 99.99% of the intense visible light from the sun. Its resilient gel film delivers high-quality images of the sun that are sharp across the entire field of view. The filter housing is made from a lightweight and durable aluminum alloy with a scratch-resistant finish.
Outfitted with three thumbscrews for a secure and centered fit, this filter is designed to fit over the entire objective bell. For the correct fit, simply measure the outside diameter of the bell - including hardware like retaining rings and screw heads - and choose the size that matches the measurement with some extra room.
