Study the Sun safely with this combination of E-Series Solar Filters and our E-Series 10x50 binocular. With the white-light solar filters installed, this combo lets you safely explore the Sun at 10x magnification to see sunspots other solar phenomena. When you don't want to look at the Sun, just remove the E-Series Solar Filters from the 10x50 binocular and use it without filters to explore daytime vistas.
These 10x50 Binoculars will give you great views without having to worry about rain or damp weather conditions. At 10-power, this binocular is more powerful than typical 7x50 or 8x42 binoculars, which means you'll be able to tease out better views of night sky treasures such as star clusters and craters on the Moon's rugged surface. The binoculars' big, 50mm objective lenses collect over 50 times the amount of light that your eye can grab, so you'll be able to see many, many more celestial objects in much greater detail than with unaided eyes. Plus, with the included E-Series Solar Filters installed, the 10x50 binoculars become an ideal Sun-viewing solution so you can safely see sunspots, transits, eclipses and other solar phenomena.
Once installed on 50mm binoculars, these E-Series Solar Filters display the Sun in a pleasing, natural yellow-orange color unlike the unnatural blue shade cast by some other types of filters. The yellow-orange image of the Sun yields high levels of contrast and clarity for sharp solar views. The lightweight solar filter housings feature an inside diameter (ID) of 2.54", which means they fit binoculars whose objective lens barrels have an outer diameter between 2.38"-2.5" (60.3mm-63.5mm). Their 2.54" inside diameter makes these solar filters a perfect fit when installed on Orion 10x50 E-Series binoculars
Warning: Never look directly at the Sun through binoculars -- even for an instant -- without professionally made solar filters that completely cover the front lenses of the instrument, or permanent eye damage could result.

Also commonly referred to as "power", magnification is a measure of how much closer an object appears when viewed through the instrument. For example, a 10x binocular will make an object appear 10-times closer than it would normally appear. An object positioned 100 yards away would appear as if it was just 10 yards away in a binocular with 10x magnification. The human eye is considered 1x magnification.
For telescopes, the optical diameter (also known as aperture) is the size of a telescope's main light-collecting lens or primary mirror, measured in millimeters or inches. Telescopes with larger optical diameters collect more light, which leads to an increase in brightness and image resolution compared to smaller instruments.
For binoculars, the optical diameter (also known as objective lens diameter) is the size of each of the front-facing objective lenses of a binocular measured in millimeters. Binoculars with larger objective lenses collect more light, which increases image resolution and brightness. Binoculars with larger objective lenses are recommended for low light situations, and binoculars with at least 50mm or larger objective lenses are recommended for pleasing astronomical observations at night.
The edge-to-edge angular diameter of the image displayed in a binocular as seen by the eyes of the observer. It is an inherent specification for a given binocular design. The "angular diameter" of an object is defined as the angle an object makes (subtends) as seen by an observer.
The diameter of the circle of light exiting the binocular. Exit pupil is calculated by dividing the objective lens diameter by the binocular magnification. For example, a 10x50 binoculars has an exit pupil of 5mm (50/10=5). Knowing the exit pupil of a binocular can help determine the optimal binocular fro your needs. If a binocular exit pupil is larger than the dilation of the user's pupil, resolution is reduced since the maximum amount of light is not entering the eye. Typically under true dark adaptation a healthy human eye will dilate to approximately 7mm. This number can decrease with age and health factors.
Binocular lenses and prisms are often coated with anti-reflective material to minimize light loss as light travels through the multiple optical surfaces of a typical binocular. Coatings help maximize the amount of light transmitted through each glass surface of a binocular, so as much light as possible reaches the observer's eyes to provide a bright and sharp image.
Good lenses are at least "fully coated," with a single layer of magnesium fluoride coating applied to each air-to-glass lens surface. Multiple layers of coatings are even more effective; the term "multi-coated" means one or more air-to-glass lens surface has multiple coatings. "Fully multi-coated" optics are even better, meaning all lens surfaces have multiple layers of anti-reflective coatings applied for maximum light transmission and optimal image quality.
Porro Prisms:
A binocular prism system that contains two right-angle prisms in each barrel offset from one another, requiring that the objective lenses be spaced further apart than the eyepieces. Optically, porro prisms often perform better than their roof prism counterparts.
Roof Prisms:
A compact binocular prism system that allows the objective lenses to line up directly with the eyepieces and hence yields a more portable binocular. Roof prism binoculars lose slightly more light to reflections than porro prism binoculars. High-quality roof prism binoculars compensate for this with special optical coatings.
