ZWO - 31mm Ha 7nm Narrowband Unmounted Filter
A narrowband filter can't eliminate the effects of visible light pollution, nor can it improve the brightness of an object.
In most cases, they merely enhance the contrast between the night sky and the nebula.
The ZWO H-Alpha utilizes a 7nm bandpass and a light transmission rate of up to 80%.
The best choice for high-contrast astrophotography is the H-alpha filter, which allows you to capture the rich details of the Nebula even in areas with light pollution.
It can also reduce the transmission of other wavelengths of light, such as those produced by the artificial light sources, such as mercury vapour.
