Astrodon Narrowband filters set a new bar of performance and durability for imaging and research.

Astrodon 5nm Narrowband Filters – H-alpha 5nm

H-α (hydrogen-alpha) at 656 nm (nanometers) is deep red in color and the most popular narrowband filter. Hydrogen is ubiquitous in the cosmos and is present in emission nebula (North American, Pelican), planetary nebula (Dumbbell, Ring), Wolf-Rayet objects (Crescent, Thor’s Helmet) and supernova remnants (Veil).
