- A must-have to safely observe the sun without damaging your eyes - optical glass filter fits snugly over your telescope's aperture to block 99.9% of incoming sunlight
- Fits Orion StarBlast 4.5 and SkyQuest XT4.5 reflectors, AstroView 120 and 120ST refractors, StarMax and Apex 127mm Maksutov-Cassegrain telescopes, and other models
- Filter inside diameter is 5.81" - fits telescope optical tubes with an outer diameter of 5.56" to 5.81" with included shim materials and securing thumbscrews
- 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.
Superior to Mylar
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 in the chart below is the ideal diameter of front of telescope; filter will fit diameters up to 1/4" smaller with foam tape liner supplied.
*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.
Determining the Correct Orion Glass Solar Filter for your Telescope
A full-aperture solar filter is designed to fit over the front of a telescope. It allows safe viewing of the Sun by reducing the light by 99.99% and preventing concentrated heat from entering the telescope, which could cause injury to the user or damage to equipment.
If your telescope is not listed on our solar filter reference chart, you can determine the size of filter needed for your scope by taking the following steps:
Measure the maximum outside diameter (OD) of the front end of your telescope.
The solar filter sizes listed in our catalog and on our website refer to the inner diameter (ID) of the filter's foam-lined metal cell for Orion Glass Solar Filters, which slip over the front of the telescope. Choose a filter whose size matches the OD of your telescope's front end, or that is up to 0.25" larger than the front end (for Orion Glass Solar Filters only). For a filter that is up to 0.25" larger in diameter than your telescope, apply the supplied adhesive foam tabs as needed to the inside wall of the cell until the cell fits snugly over the front opening. (Note: The thumbscrews on Orion Glass Solar Filters are not intended as the sole means of securing the filter to your optical tube. A tight friction fit is required for safe usage)
