Black Friday Doorbuster Astronomik H-alpha 6nm Ccd Filter - 1.25" Round Mounted Collection [8k3fWEKd]

The Astronomik H-Alpha 6nm CCD Filter is a cutting-edge accessory designed for astrophotography enthusiasts seeking to capture the beauty of emission nebulae with exceptional clarity. This filter is meticulously crafted to enhance the contrast between celestial objects and the night sky, making it an invaluable tool for both amateur and professional astronomers.

Product Features and Specifications

The Astronomik H-Alpha 6nm filter is engineered to let the H-alpha light of emission nebulae pass through while blocking nearly the entire spectrum where CCD cameras are sensitive. This narrow bandpass filter offers a Full Width at Half-Maximum (FWHM) of 6nm, providing maximum contrast between the object and the background. Its design is optimized for instruments with aperture ratios ranging from 1:3.75 to 1:15, ensuring compatibility with a wide range of telescopes. Key features include:

• Parfocal with other Astronomik filters for easy stacking and alignment.
• 1mm glass thickness for minimal light loss and optimal performance.
• Completely resistant against high humidity, scratches, and aging effects.
• Diffraction limited, ensuring the filter does not compromise your telescope's optical performance.
• Delivered in a high-quality, long-lasting filter box to protect your investment.

Practical Uses and Benefits

The Astronomik H-Alpha 6nm CCD Filter is ideal for observing extremely dim objects, even in light-polluted areas, thanks to its high contrast enhancement. It effectively suppresses the emission lines of artificial lighting and skyglow, resulting in stunning images with vivid details. By combining this filter with the 12nm H-alpha version, you can achieve maximum contrast in HII objects while retaining stars in the final image. This filter is not suitable for solar observation and is best used for false-color imaging with matching 12nm filters for seamless image combination. The benefits of this filter include:

• Increased contrast for observing faint celestial objects.
• Enhanced image quality with reduced light pollution and skyglow.
• Compatibility with a wide range of telescopes and instruments.
• Long-lasting durability and high-quality construction.
