SSF Solar Filters

The Farpoint SSF (Simple Solar Filter) line covers safe white-light solar observation across virtually every consumer telescope in production. Each filter pairs ISO 12312-2 certified silver-coated polymer solar film with a laser-cut ABS mounting ring and ultra-adhesive hook-and-loop straps that hold securely against wind — tested at 200 mph using a backpack leaf blower aimed directly at the mounted filter.

58 SKUs cover scope tube outer diameters from 120 mm to 397 mm in 5 mm grid increments, plus six specialty sizes engineered for dense scope clusters. The lineup fits every current Celestron SCT, Apertura, Sky-Watcher, and Zhumell Dobsonian, GSO-made Newtonian and Ritchey-Chrétien, and most 3″ through 15″ refractors and Newtonians on the market.

Not sure which filter fits your scope? Use our Solar Filter Finder to match your telescope by brand and model, or by direct tube OD measurement. Watch the 200 mph leaf-blower test to see the mounting system in action.

All Farpoint solar filters are designed and manufactured in the USA.
