Askar Colour Magic 2" Duo-Narrowband D Filters

Advanced Optical Design: Askar's newly introduced Colour Magic Super D 2" Duo-narrowband filter set revolutionizes deep-sky astrophotography with cutting-edge halo control capabilities. This filter boasts one bandwidth at an ultra-narrow 6nm, perfect for isolating specific wavelengths and drastically reducing light pollution effects.
Optimized for Urban Skies: Tailored for astronomers in light-polluted areas, the Super D filter ensures that even under less-than-ideal conditions, you can capture crisp, vibrant deep-sky images. The efficient light transmission and narrow bandwidth enhance contrast significantly, revealing hidden celestial details.
Versatile Filter Options: The set includes two specialized filters: the Hα+OIII Duo-narrowband (D1) and the innovative SII+OIII (D2). This combination allows color camera users to enjoy the benefits of narrowband imaging traditionally reserved for monochrome setups.
High-Speed Telescope Compatibility: Although not exclusively a high-speed filter, the Super D has been tested and performs exceptionally well with fast telescopes, even at f/1.9. This versatility makes it an excellent choice for a variety of optical systems.
Fun and Functional: The Askar Colour Magic Super D not only delivers professional-grade performance but also makes astrophotography more accessible and enjoyable. With its superior halo control and the ability to capture detailed astronomical images, it’s an ideal tool for both novice and experienced astronomers.
Innovative Imaging Solution: By integrating the Super D filter into your astrophotography gear, you eliminate the need for multiple filters, simplifying your setup and enhancing your overall shooting experience.

This duo-narrowband filter set is designed to empower astrophotographers to push the boundaries of their craft, capturing stunning celestial phenomena with unprecedented clarity and contrast. Whether you're battling urban light pollution or looking for a filter that complements your fast telescope, the Askar Colour Magic Super D 2" is your gateway to superior astrophotography.
