Astronomik Filters H-alpha 6nm CCD M49 (67105)

Thanks to advanced MRF-coating technology, this H-alpha 6nm filter is optimized for use on devices with apertures as fast as f/4, ensuring exceptional astrophotography results. It isolates the H-alpha emission line at 656nm, providing high-contrast imaging of nebulae and galaxies while effectively minimizing light pollution. Its M49 frame, durable aluminium construction, and precise coatings make it a reliable choice for capturing deep-sky objects.
