Astronomik H-Alpha MaxFR XT Filter

This filter isolates the specific 656nm wavelength emitted by hydrogen nebulae. By blocking out light pollution and natural airglow, it significantly increases the contrast of your images, making faint deep-sky objects pop against the background sky.

Yes. The ultra-thin design is specifically engineered to minimize aberrations, which are common issues when using filters with wide-angle lenses. It maintains sharp, diffraction-limited performance even at the edges of your frame.

Exactly. A parfocal design ensures that the filter maintains the same focus point as your other compatible filters. This saves you time and frustration during long imaging sessions when you need to switch equipment quickly.

The Astronomik MaxFR XT is designed as a clip-in filter compatible with major mirrorless systems, including the Canon EOS R, Nikon Z, and Sony A7 series. Please verify your specific camera model's compatibility before purchasing to ensure a proper fit.

A 12nm bandwidth is a 'sweet spot' for many astrophotographers. It is narrow enough to effectively suppress light pollution and skyglow, yet wide enough to allow for shorter exposure times compared to ultra-narrowband filters, making it versatile for various setups.

The filter is crafted from finely polished optical glass that is both scratch-resistant and anti-reflective. It is built to withstand the rigors of field use while maintaining high transmission rates of over 90% at the target wavelength.
