Antlia Solar Discover 5Å CaK

The Antlia Solar Discover 5Å CaK assembly is designed for solar imaging and incorporates a set of light-reducing filters to reduce solar heat for safe operation during solar imaging. It is specifically engineered to enhance imaging contrast for Plages, Light Bridges, features prominent in the CaK 393.3nm line and sunspots.

Antlia Solar Discover 5Å CaKThe Antlia 5Å Ultra Narrow Bandpass Filter is built into the unit and it features a clear aperture of D12mm (B1200) and a wavelength centered on the Calcium II K-Line at 393.3nm. With its ultra-narrow full width at half maximum (FWHM) of 0.5nm, it enables the capture of details in the chromospheric.

Installation is similar to the Antlia CaK 3nm Solar Herschel Wedge, with the telescope attached at one end and the camera at the another. The metal tube is machined from aircraft aluminum CNN and oxidized. The filters are assembled within a fully enclosed tube, preventing stray light from entering.
