Astronomik H-alpha Imaging Filter

No, this specific clip-in filter is precision-engineered exclusively for the Pentax K1 camera body. It will not fit or function correctly with other camera models.

A 12nm bandpass acts like a narrow gate, allowing only the specific light emitted by hydrogen-alpha regions to reach your sensor while blocking almost everything else. This dramatically increases contrast, making it possible to capture faint nebulae even when you are shooting from light-polluted urban environments.

Because of its parfocal design, you generally do not need to refocus your telescope after swapping this filter in. It is designed to maintain the same focal point as your other equipment, allowing for a seamless workflow during your imaging sessions.

A 96% transmission rate is exceptionally high, meaning very little light is lost as it passes through the glass. This efficiency allows you to maintain shorter exposure times compared to lower-quality filters, helping you capture more detail without excessive noise.

Yes, the filter is built with a moisture and scratch-resistant coating specifically designed to withstand the rigors of outdoor astrophotography. It is a robust piece of glass intended for long-term use in the field.
