Scientific celestial telescopes are located on islands or in sparsely populated regions for a reason. The steadily increasing light emission from cities and metropolitan areas, also called Light smog or light pollution marked, makes the observation and photography of stars or other celestial objects extremely difficult. The uncomfortable veil also interferes with "normal" night shots and city panoramas. DSLR and DSLM photographers are available Reducing the effects of light pollution now the new Rollei Astroklar night light filter to disposal. The artificial light sources that cause the greatest light pollution are sodium vapor lamps with a light wavelength of approx. 590 nm and mercury vapor lamps with a light wavelength of 545 nm and 580 nm their surroundings.

Less light smog, more detail and clarity

A special coating removes most of the yellow and orange light waves from the lightthat are largely responsible for the annoying light curtain. Above all, not only images of the night sky and the stars gain significantly in contrast and clarity, the advantages of this high-quality special rectangular filter, which can be used both in150mm as well as 100mm width is available now. With architectural or long-term exposures in an urban environment, even filigree structures and contrasts are retained in the motif and no longer "tear out". Due to the extensive filtering of the warmer light components, your recordings will generally be a bit cooler, so always carry out a manual white balance and choose oneColor temperature between 700 K and 1,500 K K of the spectrum without using a filter to ensure the color authenticity of your images.

Best optical glass, double-sided nano-coating

So that you can use your Rollei Astroklar filter even in demanding projects and under adverse weather conditions, the high-quality optical glasses are treated with a special nano-coating on both sides. This additional protective layer not only reliably prevents reflections from uncontrollable light sources, which are particularly annoying when shooting at night, but also has a strong water, oil and dirt repellent effect. The cleaning of your Astroklar rectangular filter becomes child's play if at all necessary. The light transmission when using the Astroklar filter is reduced by a 2/3 stop or f-stop. We generally recommend not only when combining with other filters such ase Gray filters,Polarizing filters andGraduated gray filters in the filter holder, the use of aTripod and / or oneRemote release.
