Calcium-K Modules
In the light of the calcium line (393.4 nm), interesting and scientifically important insights can be obtained with modern cameras. These modules separate this spectral range in a narrow band for the highest contrast, also visually.
The Antlia Solar Discover CaK 5Å solar filter is designed to optimize the contrast of images of flares, supergranulation cells, flares, sunspots and other visible features in calcium K (CaK) light at 393.3 nm by using very narrow bandpass filters.
Antlia Solar Discover 5 Ångström CaK calcium filters for extremely high-contrast solar photography
- Telescope side connection is 1.25" and 2"
- Camera side connection is 2" with ring clamp
- Transmission at 393.3 nm - FWHM is only 0.5 nm or 5 Angstroem
- Provides extreme contrast of sunspots, granulation and flares on the solar surface
- The filter is not intended for visual observation
- Free aperture of 12 mm
- For telescopes from 100 mm aperture we recommend an ERF filter in front of the objective for safe use
- The filter is optimized for refractors with a focal ratio of f/7 or higher. The optional Barlow lenses from Antlia can be integrated into the filter
