    How to measure your finder scope

    This affordable solar filter fits any Orion 50mm finder scope, so you can accurately aim your solar filter-equipped telescope at the Sun with a properly protected finder scope.

    To view the Sun safely with a telescope, a specialized filter that covers the entire front aperture of the telescope is required in order to protect your eyes and the telescope's optics from harmful, magnified sunlight. Interestingly enough, the Sun can be difficult to center in a telescope that has a solar filter installed. This may seem like it should be a relatively easy procedure, but trust us, it's not! In many case, your telescope may be pointing just off the limb of the Sun, leaving an entirely black view in the telescope eyepiece. By installing this E-Series Safety Film Solar Filter on any 50mm Orion finder scope, you can precisely aim your protected telescope at our nearest star, so you can observe sunspots, eclipses, and more with welcome accuracy.

    The Orion 2.32" ID E-Series Safety Film Solar Filter features a lightweight, yet rigid cardboard solar filter housing and a black-polymer film material that is stronger and more durable than other thin film solar filters. In addition, the black-polymer filter displays the Sun in a pleasing, yellow-orange color unlike the white, or especially unnatural blue shade cast by some other filter materials. The yellow-orange image of the Sun will yield high-contrast, clear views. 

    A strip of adhesive-backed felt is included to help ensure a secure friction-fit of the filter on an Orion 50mm finder scope.

    *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.

    This solar filter is designed and manufactured in the USA.

    Orion assures that all solar filters are tested at specialized labs that are accredited to verify compliance with the ISO 12312-2 safety specifications for solar viewing.

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