Antlia Filters CaK 3nm Solar Filter- 1.25"

Antlia Filters CaK 3nm Solar Filter- 1.25": Precision Imaging for Solar Observations

The Antlia Filters CaK 3nm Solar Filter- 1.25" is an exceptional tool for astrophotographers aiming to capture detailed images of the sun. Featuring a high-quality, heat-resistant, double-polished substrate, this filter is designed for use with the Antlia Solar Wedge prism. The CaK 393.3nm solar filter is equipped with advanced multicoatings, creating a sharp 3nm narrow bandpass that enhances contrast and resolution for imaging sunspots, solar granulation, and other features in CaK light.

Key Features:

• Advanced Multicoatings: Provides a sharp 3nm bandpass, ideal for high-resolution solar imaging.
• High Blocking Specification: OD5 (0.001%) between 200-1200nm and OD3 (0.1%) between 1200-1500nm wavelengths for superior resolution.
• Specialized Bandpass: Focuses on the CaK line at 393nm, highlighting specific solar features.
• Optimized for Imaging: Designed for use with cameras sensitive beyond human vision, not recommended for visual observation due to the near-invisibility of CaK features to the naked eye.
• Safety Warning: Never use the filter for direct solar viewing; it's intended for imaging purposes due to harmful UV radiation.
• Compatibility: Seamlessly integrates with Antlia Herschel Wedge Prism, eliminating the need for separate purchase.

The Antlia Filters CaK 3nm Solar Filter- 1.25" is a vital addition for solar astrophotographers seeking to delve into the intricate details of the sun's surface, offering unparalleled imaging capabilities and safety features.
