The perfect mounting cell for eclipse photographers

AstroSolar film is the standard for white light solar filters. This mounting cell has two great advantages for eclipse photographers. The wide flange shades your camera avoiding overheating. The external 3 rubber bumper attachment is easy to remove and replace quickly without disturbing your aim. This is a great advantage for totality in a total solar eclipse. Highly recommended

Make your celestial observations clearer and more detailed with the 50mm AstroSolar Binocular Filter. This innovative product, crafted by the reputable Baader Planetarium, is designed to enhance your viewing experience by reducing light pollution that can interfere with the quality of your view.

This high-quality filter is constructed with Baader AstroSolar Safety Film OD 5.0, a material renowned for its ability to maintain the true optical quality of your viewing equipment. Unlike many ready-made filters, this product does not stretch the filter material like a drumhead, which can degrade image quality. Instead, the AstroSolar film is mounted entirely stress-free, performing like a high precision plane optical window.

The filter is cell mounted and quality inspected by skilled members of the Baader Planetarium staff, ensuring a product that meets the highest standards. It features a clear white IR-rejecting front ring with reinforcing raised edges along the outer and inner circumference, designed to protect the solar filter material from contact with any sharp metal edge.

The filter is easy to mount with no tools required, and it includes adjustable centering bolts to fit a wide variety of mechanical tube diameters. It also features non-rotating sliding fasteners made from aluminum that hold the centering bolts, equipped with a machined indicator to point towards the adjustment index.

For added convenience, the filter includes an index scale provided beside each adjustment slot, allowing for fast and repeatable adjustment of the filter cell onto different telescope tubes. It also comes with three security straps to ensure a secure fit in front of the telescope under any circumstances.

Perfect for use with binoculars and camera lenses, the 50mm AstroSolar Binocular Filter is a must-have for any astronomy enthusiast. It's not just a filter, it's a gateway to the cosmos, providing a clearer, more detailed view of the stars and planets. Experience the difference with the 50mm AstroSolar Binocular Filter.
