Hydrogen-Alpha is the most dominant emission line in star-forming regions. H-Alpha light, at 656nm, is created by atomic hydrogen, and is responsible for the red color seen in most nebulae. Explore one of the main building blocks of our universe by imaging in Hydrogen-Alpha with a ZWO ASI camera, a filter wheel, and this narrowband filter!
The ZWO Ha 7nm Filter is mounted in a metal 1.25" cell and comes in a protective plastic case. ZWO narrowband filters are fine-optically polished to reach an accuracy of 1/4 wave. Their performance is further enhanced by multiple layers of anti-reflection coatings.
Please Note : This filter is for imaging the night sky in the Hydrogen Alpha bandpass; this is NOT to be used for viewing the sun.
