ZWO 1.25" H-Alpha 7 nm Filter
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! H-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.
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.
