|Duo-Band OSC Filter
|OIII (7nm) & HA (7nm)
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
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.
With the help of Dual-Band Nebula Filters, you can take deep space photography in urban areas with serious light damage.
With the help of Dual-Band Nebula Filters, you can simplify and reduce the difficulty and tedious lines in post-processing.
Dual-Band Nebula Filters can realize single exposure to capture large full-color images.
Useful for imaging emission nebulae, planetary nebulae and supernova remnants.
