Orion Glass Solar Filter Highlights

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.

Orion full-aperture optical glass filters deliver superb views of the Sun, without risk to your eyes. While more expensive than Mylar filters, many people prefer glass solar filters for their contrast, their natural yellow-orangecolor rather than blueand are considered more durable. Theyre ideal for photographing the Sun, too.

The glass elements of these Orion solar filters 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 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.
