Orion 5.81" ID Full Aperture Solar Filter

Ready to do solar astronomy? Turning your telescope to the Sun is fun and educational, but only if done safely! 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 a genuine safe, protective solar filter, even for an instant, can permanently damage your eyes! The Orion 5.81" ID Full-Aperture Solar Filter is superior to inexpensive Mylar types.

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 easier to clean too. They're ideal for photographing the Sun!

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

This Each Orion filter is mounted in an aluminum cell that slide-fits over the front of your telescope.
