SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

Unlike many white-light solar filters that produce views of the sun with a red-orange, bluish, or yellow tint, the Alpine Astronomical 100mm Baader AstroSolar White-Light Solar Filter reveals the sun in its natural white color to show more surface details with greater clarity. The filter is mounted onto a clear-white IR-rejecting plastic ring, which acts as stabilizing element for the filter cell, and the ring is in turn mounted onto the aluminum front frame. The thermal expansion coefficient of the plastic and the film are similar to minimize thermal stress on the film for increased resistance to developing pinholes or tears.

With the ability to be installed on the outside or inside of a binocular optical tube or camera lens, this filter provides a safe way to view the sun or to capture images with a camera. To fit most binocular configurations, one side of the filter housing is cut off and should be installed on the inside of the optical tube to prevent the housings from interfering with each other when the bridge is nearly closed. Recommended for objectives from 90-110mm, the filter is engineered with three centering bolts that can fit housings and lenses with an outside diameter of 105-120mm, or an inside diameter of 131-46mm (if inside-mounting is possible). Installation and removal is quick and easy with no tools or permanent modification to the optic or lens required. This is a single solar filter, for proper use on binoculars two filters must be ordered.

Fit
  • For the correct fit, measure the outside or inside diameter of the binocular optical tube or lens housing - including hardware like retaining rings and screw heads - and choose the size that matches the measurement with some extra room
  • Recommended for 90-110mm objective lens diameters
  • 131-46mm inside diameters
  • 105-120mm outside diameter
