Product Description The phenomenon of ever-increasing light smog not only affects the quality of nightly city and architectural photography, even scientific astro photography is almost impossible in urban conurbations. The large mirror telescopes therefore stand on mountain peaks, islands or in deserted areas without noticeable 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. Thanks to a special coating, the Rollei Astroklar round filter largely reduces the unwanted yellow and orange components of the light and ensures that even difficult structures and transitions are still reasonably displayed and do not "tear 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 clearly on the astro photo. Choose between four common lens diameters for astro and city photography - the Rollei Astroklar Circular Filter is available in 39, 40.5, 49, 52, 55, 58, 62, 67, 72, 77, 82, 86, 95 and 105mm. Due to the special anti-light smog coating, your shots are slightly cooler, the blue and green content understandably prevails. To counteract if necessary, you should perform manual white balance when working with the astro clear filter. Our recommendation: Choose a colour temperature between +700K and +1500K of the white balance performed without filters to get authentic colours in the final result.
