ZWO Narrowband 1.25" Filter Set Ha SII OIII 7nm

The ZWO Narrowband 1.25" Filter Set Ha SII OIII 7nm is a set of three narrowband filters designed for astrophotography. These filters are used to capture images of specific wavelengths of light emitted by nebulae, galaxies, and other celestial objects.

The Ha, SII, and OIII filters have a narrow 7nm bandwidth, allowing for enhanced contrast and detail in images. The Ha filter captures the hydrogen-alpha emission line at 656.3nm, while the SII filter captures the ionized sulfur emission line at 672.4nm, and the OIII filter captures the doubly ionized oxygen emission line at 500.7nm.

Each filter in the set is 1.25 inches in diameter, making them compatible with most astrophotography cameras and telescopes. They are constructed with high-quality materials to ensure durability and accuracy, and they come with a protective case for safe storage and transport.

With the ZWO Narrowband 1.25" Filter Set Ha SII OIII 7nm, astrophotographers can capture stunning and detailed images of the cosmos with ease.
