Svbony 7nm Dual-Band Nebula Filter Ha & OIII

Dual Narrow bandwidth H-Alpha/O-III 7nm narrowband filter properly designed for astrophotography both in light polluted
Take color images without needing to combine images with multiple filters
Useful for imaging emission nebulae, planetary nebulae and supernova remnants
Designed to sharply cut off the inference of artificial light from sodium vapor or mercury vapor street lights and other unwanted disturbance like sky glow

SV220 Dual-Band 7nm Nebula Filter

Dual Narrow bandwidth H-Alpha/O-III 7nm narrowband filter properly designed for astrophotography both in light polluted
Allows for imaging in bright man-made light pollution and moonlit conditions
Take color images without needing to combine images with multiple filters
Most useful for One-Shot Color cameras
Useful for imaging emission nebulae, planetary nebulae and supernova remnants
High transmission and sharp cut-off can greatly enhance the contrast and bring out the most detailed information for those deep-sky objects
Designed to sharply cut off the inference of artificial light from sodium vapor or mercury vapor street lights and other unwanted disturbance like sky glow
The duo-band narrowband filter is not suitable for visual observation and not designed for imaging or observing the Sun
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.

Svbony 7nm Dual-Band Nebula Filter

I have to admit this is an excellent filter, currently used with a ZWO294MC Pro camera. I have used it with a 130mm APO and Sigma 150mm lens and the images of objects like the Veil Nebula and North American Nebula show exceptional details.

An excellent investment!!!

Svbony 7nm Ha OIII narrowband filter.

This is my second Svbony 7nm filter I like the the quality of the images, I will recommend this filter for narrow band Astrophotography.

Awsome ! Big bang for your buck
This Duel- band 7 nm filter is on steroids delivers superior results in Ha and Olll with a nice dark background, star images are well defined with very little halo as compared to other well known brands. This is a must have if you are dealing with light pollution or a full moon during your imagine session
