Astronomik Filters H-alpha 6nm Clip Pentax K (67103)

Thanks to advanced MRF-coating technology, this H-alpha 6nm filter is designed for use on devices with apertures as fast as f/4, providing exceptional astrophotography performance. It isolates the H-alpha emission line at 656nm, ensuring high-contrast imaging of nebulae and galaxies while effectively reducing light pollution. The Clip-Filter has been successfully tested with Pentax K1 and K1 MkII bodies, guaranteeing compatibility and reliable operation. Its durable aluminium construction and multiple coatings ensure long-lasting quality.
