Chroma Technology Luminance Filter

This filter is designed to block ultraviolet and infrared light while allowing visible light to pass through. By cutting out those non-visible wavelengths, it helps you capture cleaner, more accurate color data in your astronomical images.

No, you shouldn't need to. This filter is parfocal with other standard Chroma filters, meaning it maintains the same focal point so you can swap filters without adjusting your focus.

This filter is optimized for focal ratios of f/4 or slower. If you are using a very fast system, you may want to verify your specific optical train requirements, but it performs reliably within that f/4 range.

Unlike filters that use laminations, this model uses durable, sputtered hard coatings applied directly to the glass. This construction is more resistant to environmental shifts, ensuring the passbands remain stable over time.

Yes. It features anti-reflection coatings on the rear surface specifically designed to maximize light transmission and minimize ghosting, which helps keep your images sharp and free of unwanted artifacts.

Yes, the filter is threaded specifically for 2-inch eyepieces and accessories, making it a straightforward drop-in addition to most standard imaging trains.
