Hi, here is a NEW premium Seymour Solar SF950 front-mounted Helios glass solar filter. Engineered to provide exceptional optical clarity while prioritizing maximum eye protection, this professional-grade filter blocks 99.999% of intense incoming sunlight, making it entirely safe for tracking eclipses, analyzing moving sunspot groups, and studying solar surface granulation.

The premium Type 2 Helios optical glass is mounted inside a durable, lightweight aluminum outer cell. It is designed to slide directly over the front barrel of popular 8-inch telescopes, rendering the sun in a pleasing, natural warm yellow-orange hue.

Key Features:

• 99.999% Light Suppression: Completely blocks harmful infrared (IR) and ultraviolet (UV) radiation for absolute visual and photographic safety.

• Premium Aluminum Cell (SF950 Sizing): Heavy-duty 9.5-inch (241mm) aluminum frame engineered to slip over optical tube outer diameters (OD) measuring roughly 9.125" to 9.375" (232mm to 238mm).

• Secured Three-Screw System: Equipped with three nylon-tipped thumb screws along the collar rim to cinch the housing snugly onto your telescope without scratching the paint finish.

• Natural Solar Details: High-reflectivity Type 2 glass delivers a sharp, high-contrast orange/yellow image of the sun's disk rather than an artificial blue tone.

• Wide 8" Telescope Compatibility: Perfectly fits a broad array of 8-inch optical tubes, including the Celestron NexStar 8SE, Evolution 8, Advanced VX 8" SCT, EdgeHD 800, Meade LX90/LX200 8", and various 8-inch reflector/Dobsonian setups.
