ZWO Ha narrowband filter 36 mm
Narrowband filter does not eliminate the effects of light pollution or increase the object’s brightness. In many cases, they increase the contrast between the nebula and the night sky, not brightening the nebula.
It can reduce the transmission of certain wavelengths of light, specifically, those produced by artificial light including mercury vapor, and both high and low-pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).
From 2018, ZWO Made progress on narrowband filters with the new standard, providing better performance.
