Rollei Astroklar Round Filter
The phenomenon of ever-increasing light smog not only impairs the quality of nocturnal city and architectural photographs, even scientific astrophotography is virtually impossible in urban conurbations. The large reflecting telescopes are therefore located on mountain tops, islands or in deserted areas without perceptible light pollution. "Normal" professional and amateur photographers can now use the new Rollei Astroklar round filter to reduce the unwanted effect of light pollution and give their shots more contrast and clarity.
Works reliably against light pollution...
Thanks to a special coating, the new Rollei Astroklar round filter largely reduces the unwanted yellow and orange components of the light and ensures that even delicate structures and transitions are still displayed reasonably and do not "break out". The night and starry sky, partially or only sparsely illuminated building panoramas gain significantly in contrast and drawing, even extremely distant and barely visible stars can appear clearly and distinctly on the astro photo. Choose between four popular Lens diameters for astrophotography and city photography - the Rollei Astro Clear Round Filter is available in 67, 72, 77 and 82 mm. Due to the special anti-light smog coating, your images will turn out a bit cooler, the blue and green parts understandably predominate. To counteract this, you should perform a manual white balance when working with the astro clear filter. Our recommendation: select a color temperature between +700 K and +1,500 K of the white balance performed without the filter to obtain authentic colors in the final result.
...reliably keeps out water, oil and dirt
The enormous suitability for everyday use of the new Rollei Astroklar round filter is ensured by a complex nano-coating on both sides of the high-quality optical glass. This coating permanently reduces unwanted light reflections, which can ruin the entire shot, especially during long exposures at night. Furthermore, the protective coating repels dirt, oil, and water almost like a magnet; you simply remove any residue with a quick wipe of the care and cleaning cloth. The anti light smog coating of the Astroklar round filters results in a reduction of the general light transmission by a 2/3 f-stop. Regardless of whether you use the filter individually or in combination with other optics, the use of a tripod and a cable or wireless shutter release ensures that you can save not only high-contrast and detailed astro or nighttime images, but also razor-sharp images to your camera's memory card.
