Light pollution is one of the main problems of every astrophotographer, no doubt about that. If you want to get rid of its orange-yellowish tint, you need either post-processing or a filter. We have recently presented you with PureNight Premium, a filter you can attach to your camera and reduce the effects of light pollution. It’s mounted onto your lens by using a standard square filter holder.
But Cyclops Optics, a Hong Kong-based company has another solution. They produce filters that can be clipped on – but onto your camera’s sensor.
STC Astro-Multispectra Clip Filters have been available for Canon full frame cameras. But the company has recently launched the clip-on filters for full frame Nikon as well.
The goal of these filters is to reduce the light emissions from mercury and sodium street light. This way they remove the tint from street lights, but at the same time they allow the light from the stars to pass. This gives you accurate colors and enhanced contrast of stars and improves overall picture quality.

The setup of the filter is easy and quick. You need to enable the mirror lock-up function, remove the lens and lock the mirror up. Then, you only need to clip the filter onto the sensor, put the lens back on and that’s it. You can see how it looks like in this video:
Personally, I find this solution interesting, but the thought of approaching the sensor with my fingers terrifies me. I’d rather choose a regular filter or spend some extra time editing the photos. But that’s just me. What do you say? Would you use this kind of filter? Share your thoughts in the comments.
