ANTLIA Solar Discover 5A CaK Kit Astronomical Accessory for Solar Heat Intrusion Reduction
Description:
- Antlia Solar Discover 5A (0.5nm) CaK is a component composed of an adapter ERF, Antlia 5A (0.5nm) CaK 393.3nm, and a filter, which maximizes the imaging contrast of sunspots, solar surface particles, CaK 393.3nm lines, solar spectral patterns, and other prominent features. Compared to 3nm CaK, it is also very excellent on the upper surface of the chromosphere. Significantly better than the surface on a 3nm optical sphere layer.
- This component includes an Antlia 5A (0.5nm) ultra narrow bandpass filter with a wavelength centered around CaIIK 393.3nm. The high barrier specification of OD5 (0.001%) at 200-1200nm wavelength can reduce the intrusion of solar heat. This heat reduction system can effectively maintain the instrument at a safe operating temperature, thereby extending the service life of the equipment.
- It is worth noting that due to the low sensitivity of the eyes to CaK frequency, the bandpass of CaK (393nm) makes it almost impossible for the human eye to see the characteristics of the sun. Therefore, it is not recommended to use the Antlia Solar Discover CaK component for visual observation.
- Eyepiece design is used for the Antlia Solar Discover 5A (0.5nm) CaK 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 metal ring machined from aircraft aluminum CNC and oxidized. The filters are assembled in a fully closed barrel. No stray light can escape from this.

- Businesses may need to employ various types of legal pages on their websites or mobile apps. Some, like Privacy Policies, are required by law, while others, such as a Terms and Conditions agreement (T&C), are not. Regardless of legal demands, you may find that your company needs one or more legal pages for compliance and optimal operation.
- In this article, we will go over the most common legal pages, walk you through a summary of what each requires, and explain why you may need it. In addition, you'll find a sample template for each type of legal page so you can quickly get started writing your own.
