Solar Filters 125-155 mm

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.
