Orion Solar Filter Sets for Binoculars
Accepted Payment
  • Designed to fit snugly over the front apertures of your binoculars, these optical glass filters block 99.999% of incoming sunlight, allowing you to safely observe sunspots and solar granulation
  • Using binoculars equipped with these white light solar filters to view sunspots and the solar surface gives you an added sense of depth thanks to using both eyes
  • Each filter has three nylon thumbscrews to ensure a snug fit to the front of your telescope or binocular
  • The thumbscrews complement the press-fit foam lining inside the filter's durable aluminum cell to accommodate diameters up to 1/4" smaller than the nominal size
  • The glass elements are machine-polished and triple-coated with nickel-chromium stainless steel for a scratch-resistant surface

Who said you have to be in the dark to enjoy astronomy? Turning your pair of binoculars 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 Full Aperture glass Solar Filter Set for Binoculars! Looking at the Sun without a set, even for an instant, can permanently damage your eyes.

These full-aperture optical glass binocular filters deliver superb, white-light views of the Sun, without risk to your eyes. While more expensive than film filters, Orion glass solar filters provide better contrast, a more pleasing and natural yellow-orange color, and are more durable. They are ideal to use with your binoculars for safe views of our Sun. 

The glass filter 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 filter is mounted in an aluminum cell that slide-fits over the front objective lenses of your binoculars. Three nylon thumbscrews can be tightened to ensure a safe, snug fit to the front of your binoculars. The thumbscrews complement the press-fit foam lining inside the durable aluminum filter cell. A tight friction-fit is still required for safe solar viewing through a pair of binoculars.

 

*WARNING! When using a truss tube Dobsonian telescope for solar observing, always use a Light Shroud and a properly sized solar filter. When you install the Light Shroud make certain there are no gaps between the Shroud and the telescope where direct sunlight can reach the telescope mirror. When a truss tube telescope (equipped with a solar filter but no Light Shroud) is pointing near (not at) the Sun, direct sunlight can hit the mirror and focus on the solar filter or other portions of the telescope. This can lead to eye injury or damage to the telescope. Using a Light Shroud protects your telescope from peripheral sunlight.

Before using any telescope for solar observing, make sure to install all dustcaps or other protective covers on all optical components such as finder scopes to keep sunlight from passing through them. Glancing through an uncovered optical system, even for an instant, can cause permanent eye damage. Always install protective caps on all optical instruments if left out during daylight hours.  

CAUTION: Never look at the Sun, even for an instant, without a protective solar filter. Doing so can permanently damage your eyes.
