The Sirius 2 inch UHC Skyglow Broadband CLS Filter effectively reduces light pollution, enhancing contrast and detail when observing or imaging deep-sky objects from urban and suburban locations. Designed to fit standard 2-inch eyepieces and accessories, this broadband filter selectively blocks artificial light while transmitting key nebula and star wavelengths for clearer, more vibrant views of the night sky.

This Sirius Optics adapter seamlessly connects 2-inch push-fit accessories to telescopes and components with a standard SCT (Schmidt-Cassegrain) male thread. Featuring a precision SCT outer thread on one end and a 2-inch push-fit nosepiece with a built-in 2-inch filter thread on the other, it's ideal for use with SCT-threaded star diagonals, focal reducers, and other accessories from brands like Celestron and Meade.
