SV220 Dual-Band H-a 7nm & OIII 7nm Filter
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.
SVBONY SV220 Dual-band 7nm Filter
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.
Greatly Reduce the Effect of Light Pollution & Moonlight
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.
More Simplified for Photography and Post-processing
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.

These evenings I'm trying to make a difficult subject that all astrophotographers would like and I think they dream of doing, (but from darker skies, I'll try "it's a DELIRIUM 😁") if it goes well, I hope that next month I'll finish it 😅 after having taken it until about 10.30 pm, I pointed the telephoto on this beautiful Nebula, since the night allowed it.
IC 410 (Tadpole Nebula) NGC 1983
IC 410, sometimes known as the Tadpole Nebula because of its north-eastern filaments, is a large emission nebula visible in the constellation of Auriga; the open cluster NGC 1893 is linked to it, formed by young massive stars rather dispersed. The region is home to important star formation processes generating stars of great mass. Its distance is about 19,640 light years.
