## Overview

The SVBONY SV220 is a 1.25-inch dual-band narrowband filter designed for astrophotography with one-shot color cameras. It targets H-Alpha and O-III wavelengths with 7nm bandwidths to dramatically reduce light pollution and moonlight interference, enhancing contrast and detail in nebula imaging. Compatible with most telescopes and cameras, it simplifies setup and post-processing, making it ideal for urban astrophotographers seeking crisp, high-contrast deep-sky images.

## Description

SVBONY H-Alpha/O-III 7nm Narrow Band Dual Narrow Band Filters are specially designed for astrophotography in light-polluted environments, allowing imaging in bright artificial light pollution and moonlight conditions to capture color images without using multiple filter combinations. Images are most useful with single-use color cameras; it can be used to image emission nebulae, planetary nebulae and supernova debris; high transmittance and sharp cutting can greatly improve contrast, showing the most detailed information about deep sky objects; designed to drastically remove sodium. Artificial light interference from vapor or mercury streetlights and other unwanted interference (e.g. sky brightness); Dual-band narrowband filters are not suitable for visual observation and are not designed for imaging or observing the sun. Note that the SV220 is not suitable for fast telescopes; some users have reported that dual-band OSC filters combined with RASA can cause band changes, thereby clipping HA data.
