Orion Solar Filter -
9.25" SCT

You don't 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.

Superior to Mylar
These full-aperture optical glass filters deliver superb views of the Sun, without risk to your eyes. While more expensive than Mylar filters, Orion solar filters provide better contrast, a more natural yellow-orange—colour rather than blue—and are 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.

The filter cell has an inside diameter of 258.1mm and will fit diameters as much as 6mm smaller with foam tape liner supplied.
