  • More Info
    • A must-have filter for safely observing the Sun through an 11" Schmidt-Cassegrain telescope without damaging your eyes
    • Solar filter with a 12.31" inside diameter fits snugly over your telescope's front aperture to block 99.999% of incoming sunlight
    • Glass elements are machine-polished and triple-coated with nickel-chromium stainless steel
    • Each Orion telescope solar filter is mounted in a foam-lined aluminum cell featuring three equidistant securing thumbscrews, 4x 1/16" thick adhesive foam tabs, and 4x 1/8" thick adhesive foam tabs for customized friction fit to your telescope
    • Note: All Orion solar filters are designed for use with an adequate friction fit attachment. Thumbscrews should ONLY be used to keep filter securely in place once a friction fit has been achieved

    Who said you have to be in the dark to do astronomy? Turning your telescope to the Sun is fun and educational. Watch the march of giant sunspots, the clouds of glowing vapor in the photosphere, and solar "granulation" detail. But be sure to protect your precious vision with a safe Orion solar filter! Looking at the Sun without one, even for an instant, can permanently damage your eyes.

    These full-aperture optical glass telescope filters deliver superb views of the Sun, without risk to your eyes. While more expensive than Mylar filters, Orion glass solar filters provide better contrast, a more natural yellow-orange color instead of blue, and their glass and aluminum construction is much more durable. They're ideal for photographing the Sun too!

    The glass elements are machine-polished and triple-coated with an advanced nickel-chromium stainless steel alloy for a scratch-resistant surface. The filter passes only a fraction of the incoming light, rejecting harmful ultraviolet and infrared radiation.

    Each Orion filter is mounted in an aluminum cell that slide-fits over the front of your telescope. Size shown is the ideal diameter of front of telescope; filter will fit diameters up to 1/4" smaller with foam tape liner supplied.

    CAUTION: Never look at the Sun, either directly or through a telescope, without a professionally made protective solar filter installed that completely covers the front of the instrument, or permanent eye damage could result.
