The Antlia Solar Discover Dualband (Ha, CaK, and CaH) filter assembly comes in both standard and mini versions. The standard version (this item) is compatible with both 1.25'' and 2'' adapters, while the mini version is designed for 1.25''. This product is specifically designed for solar photography, effectively enhancing contrast and sharpness in solar imaging. This results in greater visibility of surface details and highlights of sunspots, while also providing higher contrast for solar faculae.
The complete assembly comes with a Antlia Energy Rejection Filter (ERF) filter, which functions to block far UV and IR light as well as being a ND filter. This allows the desired wavelengths Ha 656.3nm, CaK 393.3nm, and CaH 396.8nm to pass through.
Features
- A new tube design is used for the Antlia Solar Discover Dualband filter assembly. Installation is similar to the Antlia CaK 3nm Solar Herschel Wedge, with the telescope attached at one end and the camera at the other. The filters are assembled in a fully closed tube and the metal tube machined from aircraft CNC aluminum and oxidized. No stray light can escape or enter.
- Compared to other solar reducing films, the Antlia Solar Discover Dualband filter assembly offers superior advantages: It enables higher contrast for solar imaging, higher resolution of the solar surface detail, and the design is less susceptible to wear and tear. Additionally, its user-friendly, ensuring ease of use, and boasts the extended lifespan for your equipment used for solar imaging.
- It can be directly used for solar photosphere imaging, such as sunspots.
- 1.25" and 2" Adapters
- The Antlia Solar Discover Dualband Ha, CaK and CaH filter assembly combines the 1.25'' and 2'' adapter used in astrophotography for easier and faster connection of the telescopes and camera.
Important Notes:
- When you are using a diagonal mirror, the ERF filter must be installed in the correct position for safe operation. Please refer to the installation diagram.
- When you are using a telescope with an aperture >100mm, you need to use additional light reduction solutions, such as ERF filters, solar safety films, lowering the telescope aperture for safe operation while using the Solar Discover Dualband Ha, CaK and CaH filter Assembly; if used without the extra light reduction, the Solar Discover Dualband Assembly can only used with REFRACTORS up to 100mm aperture.
Important Notes:
-
The IR coating range of Antlia products is slightly different from the ISO 12312-2 Standard for Solar Viewers, please see the following chart and refer to ISO 12312-2 Standard for Solar Viewers (https://eclipse.aas.org/eye-safety/iso12312-2).
-
The Solar Discover Dualband Ha, CaK and CaH filter assembly is not recommended for visual observation.
Warranty:
- 3 years
- Disassembly of the assembly is prohibited and voids warranty. Any repair/returns/exchange for this item is not accepted once it has been disassembled.
