SVBONY SV227 Telescope Filter 2", OIII 5nm Narrow-Band CCD Filter, Light Pollution Filter Improve Contrast Bundle with SV241 Astronomy Telescope Power Adapter for Deep Sky Astrophotography

The SCBONY SV227 OII filter is designed for nebula observation and reducing the transmission of certain wavelengths of light. The larger the optical density, the clearer the image details. You can connect to your 2 inch eyepiece and make the sky you see even better. 90% transmission - whether under dark skies or under the sky glow of a city. The thickness of the substrate can affect parameters such as wavelength and dispersion of the filter. The Full Width at Half Maximum (FWHM) is about 5 nm. The OIII filter is designed for nebula observation allowing 5nm bandwidth of light centered on a wavelength of 500.7nm through. M48x0.75 thread interface adapts to most devices. SVBONY SV241 Astronomy Power adapter is a hub specifically designed for astronomical imaging and an invaluable assistant for shooting the starry sky. It integrates a plethora of power and data interfaces, featuring exceptional industrial design and hardware protection functionalities.
