Round filter Astroklar night light filter

The phenomenon of ever-increasing light smog not only affects the quality of nocturnal city and architectural photographs, even scientific astrophotography is almost impossible in urban areas. The large reflecting telescopes are therefore on mountain peaks, islands or in deserted areas with no 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 photos 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 difficult structures and transitions are still displayed properly and do not "tear out". The night and starry sky, partially or only sparsely lit building panoramas clearly gain 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 astro and city photography - the Rollei Astroklar round filter is available in 39, 40.5, 46, 49, 52, 55, 58, 62, 67, 72, 77, 82, 86, 95 and 105mm available. Due to the special anti-light smog coating, your recordings will be a bit cooler, 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: Choose a color temperature between +700 K and +1,500 K for the white balance carried out without a filter in order to obtain authentic colors in the end result.

... and reliably keeps water, oil and dirt out

The enormous suitability for everyday use of the new Rollei Astroklar round filter is guaranteed by an elaborate nano-coating on both sides of the high-quality optical glasses. This compensation permanently reduces unwanted light reflections, which can ruin the entire recording, especially with long-term exposures at night. Furthermore, the protective layer repels dirt, oil and water almost like a magnet. Any residue can be easily removed with a quick wipe of the care and cleaning cloth.

The result: High-contrast astro and night shots

The anti-light smog coating of the Astroklar round filter reduces the general light transmission by 2/3 f-stops/stop. Regardless of whether you use the filter alone or in combination with other optics, the use of a tripod and a cable or radio release ensures that you can save razor-sharp images on your camera's memory card.

If you want to make it easier to rearrange your studio and, for example, don't want to carry tripods around all the time, we have the ideal solution for you with our tripod castors. Thanks to their smooth-running bearings and parking brakes, they are particularly easy to handle and assemble and are also suitable for quickly changing the lighting during the shoot.
