Optolong Filters Clip Filter for Canon EOS APS-C H-Alpha

The H-alpha filter, renowned for its narrowband capabilities, specifically targets light in the red wavelength at 656nm. By allowing only the narrow range of hydrogen-alpha light to pass through while blocking unwanted wavelengths, this filter unveils hidden details within hydrogen nebulae.

Equipped with a 7nm bandwidth, the H-alpha clip-filter captures intricate details and enriches nebula regions that may otherwise be challenging to photograph. It effectively eliminates disruptive artificial light, making it suitable for use even in light-polluted areas. However, it's crucial to remember that this filter should never be employed as the sole solar filter.
