Rollei Astroklar round filter
The phenomenon of ever-increasing light smog not only impairs the quality of night-time city and architectural photography, even scientific astrophotography is virtually no longer possible in urban areas. The large reflector telescopes are therefore located on mountain peaks, islands or in deserted areas with no perceptible light pollution. "Normal" professional and amateur photographers can now use the new Rollei Astroclear round filter to reduce the unwanted effect of light pollution and give their images more contrast and clarity.
Reliably combats light pollution...
Thanks to a special coating, the new Rollei Astroclear round filter largely reduces the unwanted yellow and orange components of the light and ensures that even difficult structures and transitions are still displayed reasonably and do not "tear out". The night and starry sky, partially or only sparsely lit building panoramas gain significantly in contrast and definition, even extremely distant and barely visible stars can appear clearly and distinctly on the astrophoto. Choose between four common Lens diameters for astrophotography and urban photography - the Rollei Astroclear round filter is available in 67, 72, 77 and 82 mm. Due to the special anti-smog coating, your images will be somewhat cooler and the blue and green components will understandably predominate. To counteract this if necessary, you should carry out a manual white balance when working with the astro clear filter. Our recommendation: Select a color temperature between +700 K and +1,500 K for the white balance performed without the filter in order to achieve authentic colors in the final result.
...reliably keeps out water, oil and dirt
The enormous suitability of the new Rollei Astroclear round filter for everyday use is ensured by a complex nano-coating on both sides of the high-quality optical lenses. This coating permanently reduces unwanted light reflections, which can ruin the entire shot, especially when taking long exposures at night. Furthermore, the protective coating repels dirt, oil and water almost like a magnet; any residue can simply be removed with a quick wipe of the care and cleaning cloth. The anti light smog coating of the Astroclear round filters reduces the general light transmission by 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 radio trigger ensures that you can save not only high-contrast and detailed astro or night shots, but also razor-sharp images on your camera's memory card.
