Sun Catcher Variable Large Aperture Solar Filter

The Sun Catcher covers the front of your telescope with Thousand Oaks Optical's Solarlite film for observing sunspots and solar granulation. Explore Scientific makes it in eight sizes, for telescopes from 70mm up to 12-inch SCTs, Explore FirstLight and Explore Scientific telescopes among them.

Key Features

• Explore Scientific rates it "100% Safe for Eclipse Viewing." Fit it securely over the front of the telescope, and cap or filter the finder, as NASA and the American Astronomical Society advise.
• Lightweight and generally does not require rebalancing tube assembly.
• Explore Scientific describes the film as highly tear and puncture-resistant.
• Consistent yellow-orange solar image.
• Even density across the aperture; the film lies flat.
• Thousand Oaks Optical Guarantees Solarlite Filter Material for 15 years.

Ideal For

• Eclipse chasers who want a full-aperture filter sized to their own telescope.
• Solar observers following sunspots and granulation.
• Solar imagers. Explore Scientific says the Solarlite film has the optical quality of glass with the advantages of impregnated polymer, and calls it perfect for the solar astrophotographer.

Accessories & Compatibility

Choose the size by your tube's outside diameter; each size lists the telescopes or tube diameters it fits. For 10-inch and 12-inch Dobsonian telescopes, Explore Scientific specifies SC14-00.
