Full traction texture around the entire circumference of the X4 makes it easier than ever to get off and on securely

Built to withstand extreme wind, salt water, dust and other abrasive conditions and elements

We stand behind each X4 ND to be free of defects in craftsmanship for 25 years, but they’ll easily last 50+ with proper care

ELiminate light pollution

The X4 Night Sky filter delivers incredible starlight definition and true colour neutrality. As part of the the X4 range all Night Sky filters  are weather-sealed within a rugged X4 traction frame as well as durable MRC16 and nanotec® coatings for easy and fast cleaning.


On the visible light spectrum artificial light pollution ranges between 570 to 610 nanometers . Artificial light pollution is likely to significantly reduce the definition of starlight by up to 50%. The orange colour cast common with most forms of artificial light decreases contrast between space and the stars within it, making an the otherwise black backdrop of space look orangish


Eliminating light pollution in post-processing is a destructive type of editing, whereas with a Night Sky filter light pollution is eliminated non-destructively.

Light pollution across Europe


To find a location to shoot without light pollution can be incredibly difficult if not impossible depending on where you’re shooting and to a lesser degree when you are shooting.
