Introduction:
- The SVBONY 7nm dual band filter is designed to drastically reduce the effect of light pollution, for emission nebulae, planetary nebulae and supernova remnants imaging.
- The 7nm bandwidth strongly isolates the nebulae's emissions into H-Alpha (red) and OIII (green-blue) from anything else, ensuring that the shooting astronomical object is pure enough, free from non-target spectral interference.
- The SV220 filter greatly reduces the effect of light pollution and moonlight, and makes it possible to do photography in a light polluted environmental conditions, like on your balcony or in your backyard. Meanwhile it saves your time on the road and cost on the fuel.
- Comparing to the traditional DSO photography plan “Monochrome camera + SHO filters + Filter wheel” and long single channel exposure time and post-processing, SV220 dual-band filter simplifies the tediousness and difficulties of photography and post-processing, gaining full color images with one-shot.
