The Chroma 1.25" H-alpha 3nm Narrowband Filter is a precision instrument designed for astronomers seeking to capture the beauty of ionized hydrogen atoms within nebulae. This filter is crafted with the highest quality materials and advanced manufacturing techniques to ensure exceptional performance and durability. It is an essential tool for imaging objects rich in hydrogen atoms, even in heavy light-polluted areas or when the moon is up, allowing for stunning observations under various conditions.

Optimized Performance and Durability

The Chroma filter features an innovative coating that is angle-sensitive, specifically optimized for F/3 beams. This design shift minimizes the blue shift that can compromise transmission at the desired wavelength, ensuring maximum efficiency and clarity. The filter is made with durable, sputtered hard coating on a single substrate of premium glass, eliminating the need for laminations and ensuring long-lasting performance. All primary coatings are applied on the front surface, while anti-reflection coatings are on the rear, preventing ghosting and maximizing light transmission.

• Optimized for F/3 beams with minimal blue shift
• Single substrate of the best glass for maximum clarity

Enhance Your Observations and Images

The Chroma 1.25" H-alpha 3nm Narrowband Filter is ideal for both amateur and professional astronomers looking to enhance their observations and capture detailed images of nebulae and other celestial objects. With a transmitted wavefront better than 0.25 waves/inch and parfocal design for systems f/4.0 or slower, this filter offers unparalleled precision and accuracy. It is made in America, guaranteeing quality craftsmanship and reliability. For convenience and safety, filters up to 2-inch come with a complimentary TPO Filter Case (OS-CF2), ensuring your investment stays protected.
