Breakthrough Photography Magnetic Night Sky Filter

Why Magnetic Filters?

Less expensive to make. Less expensive to buy.

There’s approximately 15% unusable surface area on square filters, unnecessarily increasing cost to both the manufacturer and photographer. Because magnetic filters are based on a circular design, there’s no unusable surface area on the glass. As a result they’re much less expensive to make.

Breakthrough Photography’s cutting edge research and alternative manufacturing methods deliver the most colour neutral ND filter for the discerning landscape photographer. In the time that it took them to achieve the X4 ND’s unparalleled colour neutrality they also took their hand at redesigning the filter frame from the ground up.See below for reviews on Breakthrough Photography X4 Neutral Density 10 Stop Filters.

0% Light Leak

We have eliminated light leak with magnetic filters. Now, when shooting with a 15- stop ND, you no longer need to consider light leak through the lens (however light leak through viewfinder can still be an issue)

Instantly attaches.

Instantly attach magnetic filters in just a quarter of a second. Square filters require correct alignment to the holder, whereas magnetic filters precisely attach every time to the correct position. And like square filters, our new magnetic filters will work on 82mm thread sizes and smaller. Instead of buying a filter for each lens you simply need either a magnetic adapter ring or a step-up ring.

N.B. A magnetic adaptor wheel is required. 


Light Pollution Eliminated

Each Breakthrough Photography Night Sky filter delivers incredible starlight definition and true colour neutrality. Each Night Sky filter is weather-sealed in a rugged X4 traction frame and features an incredibly durable MRC16 and nanotec coatings for easy and fast cleaning.

No Night Sky Filter VS. Night Sky Filter


Built for outdoor photographers.

Artificial light pollution ranges between 570 to 610 nanometers on the visible light spectrum. Artificial light pollution can reduce starlight definition by up to 50%. The orange colour cast decreases contrast between the stars and the space behind them, making an the otherwise black backdrop of space look orangish.

Eliminates light pollution


Eliminating light pollution is essential to capturing beautiful Night Sky images, however finding a location to shoot without light pollution can be incredibly difficult if not impossible depending on where you’re shooting.

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