Antlia Imaging Herschel Wedge with 35mm Prism and 1.25'' Cak 3nm Solar Filter

Antlia Imaging Herschel Wedge with 35mm Prism and 1.25'' Cak 3nm Solar Filter

The Antlia Solar Wedge (Herschel Wedge design) replaces the standard prism diagonal at the rear of refractor telescopes to enable imaging of solar granulation and sunspots. The Herschel Wedge design is well known to give sharper, higher-contrast images. The Antlia Solar Wedge design transmits a greatly reduced, safe amount of light to your imaging camera. The image brightness can be conveniently increased or decreased using a control ring with aperture blades, similar to that used in camera lenses.

Our Herschel Wedge is produced using CNC machining and the optical components are multi-coated with anti-reflection coatings to minimize both internal reflections and contrast reducing stray light. The solar wedge incorporates an Antlia 3nm narrow bandpass filter at the Calcium II K-Line centered on 393.3nm and mounted in a standard 1.25’’ holder.

Unlike some other solar wedge designs which may get too hot, the Antlia Imaging Solar Wedge directs energy into an extra thick Polycrystalline Ceramic diffuser plate at the rear of the Wedge. In addition, cooling vents above the ceramic plate facilitate efficient cooling of the system.

The Antlia Cak 3nm solar prism system provides for the safe management of harmful light intensity and heat when imaging the sun. The system is comprised of a prism, Cak lens filter, sun centering finder and a heat dissipation system. The sun’s light passes through the right-angle prism and excess heat is transferred to the rear fins that act as a heat sink for cooling the instrument. This heat management system effectively keeps the the instrument at safe operating temperatures.

Please note:

The Antlia Herschel Wedge is intended for imaging ONLY. It is not suitable for visual observation.

It is not intended for solar prominence imaging and visual.

Must only be used with refractor telescopes to avoid damage to the unit.

Refractor aperture must be no larger than 120mm or, focal ratio of F5.5 or longer.

Never use the Solar wedge without the supplied narrowband filter. Otherwise irreparable eye damage can result.

Disassembly of prism is prohibited and voids warranty. Any repair/returns/exchange for this item is not accepted once it has been disassembled.
