The Askar 6nm Color Magic Ha/OIII & SII/OIII (D1+D2) Filter Package is a comprehensive set of narrowband filters designed for advanced astrophotography. This package includes two specialized filters: the 6nm Ha/OIII (D1) and the 6nm SII/OIII (D2), allowing astrophotographers to capture stunning, high-contrast images of emission nebulae and other deep-sky objects with vivid color separation.
These filters are designed for use with color cameras. Ensure compatibility with your imaging setup before purchase.
Filter Specifications
Both filters in this package feature a narrow 6nm bandwidth, precisely isolating specific emission lines:
1. Ha/OIII (D1): Combines Hydrogen-alpha and Oxygen III wavelengths
2. SII/OIII (D2): Combines Sulfur II and Oxygen III wavelengths
This narrow bandwidth effectively suppresses light pollution while maximizing the signal from emission nebulae.
Enhanced Color Separation
The combination of these two filters allows for excellent color separation in astrophotography. The Ha/OIII filter captures red and blue-green emissions, while the SII/OIII filter captures red-orange and blue-green emissions. This separation enables the creation of vivid, false-color images that highlight the structure and composition of nebulae.
High-Quality Construction
Manufactured with precision optical glass and high-quality dielectric coatings to ensure excellent light transmission and minimal reflections. The filters are designed to maintain their performance over time, resisting degradation from exposure to moisture or varying temperatures.
Versatile Application
Ideal for imaging a wide range of emission nebulae, supernova remnants, and planetary nebulae. These filters are particularly effective for capturing the intricate details and structures of objects like the Orion Nebula, Veil Nebula, and the North America Nebula.
Efficient Workflow
By combining multiple emission lines in each filter, this package allows for more efficient data acquisition compared to traditional narrowband imaging with single-line filters. This can significantly reduce total imaging time while still providing excellent data for creating detailed composite images.
Enhanced Contrast in Light-Polluted Skies
The narrow 6nm bandwidth of these filters effectively suppresses light pollution and skyglow, allowing for high-contrast imaging even from urban and suburban locations. This makes them valuable tools for astrophotographers dealing with less-than-ideal sky conditions.
Compatibility
Designed for use with monochrome CCD or CMOS cameras. Check the filter size and thread specifications to ensure compatibility with your telescope or camera system. These filters are typically available in common sizes such as 1.25" or 2" to fit standard filter wheels and camera adapters.
