Mild effect of darkening background of the night sky:
So that the fainter objects is more clearly seen contrasted against the blackness of space
Effectively filters out stray light:
Filtering Selective wavelengths of low-pressure sodium and other man-made sources typically used in street lighting
It enhances the views of deep-sky objects by increasing the contrast of these objects against the background sky
While nebula filters transmit only a few select wavelengths corresponding to various atomic lines
The filter transmits a large portion of the continuous spectrum while blocking a few select lines of the more common man-made light
Neodymium provides a unique;selective;blocking feature in that this element greatly reduces glare without reducing important color and brightness variations
