SVBONY SV220 Dual-Band 7nm Nebula Filter for One-Shot Color Cameras 2" Mounted

The SVBONY 7nm dual band filter is designed to drastically reduce the effect of light pollution. The 7nm bandwidth means it strongly isolates the nebulae's emissions into H-Alpha (red) and OIII (green-blue) from anything else. It blocks light pollution, maximizes the signal from nebulae, and darkens the sky background. It also blocks artificial light from mercury vapor lamps, high- and low-pressure sodium vapor lights, and unwanted natural light caused by the emission of neutral oxygen in our atmosphere.

Features:

1.Dual Narrow bandwidth H-Alpha/O-III 7nm narrowband filter properly designed for astrophotography both in light polluted2.Allows for imaging in bright man-made light pollution and moonlit conditions3.Take color images without needing to combine images with multiple filters4.Most useful for One-Shot Color cameras5.Useful for imaging emission nebulae, planetary nebulae and supernova remnants6.High transmission and sharp cut-off can greatly enhance the contrast and bring out the most detailed information for those deep-sky objects7.Designed to sharply cut off the inference of artificial light from sodium vapor or mercury vapor street lights and other unwanted disturbance like sky glow8.The duo-band narrowband filter is not suitable for visual observation and not designed for imaging or observing the Sun9.Be aware that the SV220 is not a great fit for fast telescopes, some users reported that the Duo-Band OSC Filter paired with the RASA caused band shift, thus clipping the HA data.
