  • Description

    Celestron's Rowe-Ackermann Schmidt Astrograph has made it possible for amateur astrophotographers to achieve professional-quality astroimages with a simple, affordable, compact system. But unfortunately, light pollution can sometimes stand between you and your best shot. Reduce the effects of light pollution and get high contrast images with this custom-designed Light Pollution Imaging Filter for RASA.

    Precision engineering from Celestron and Astrodon

    Celestron's team set out to create the absolute best light pollution reduction filter ever designed. To achieve that goal, they joined forces with Astrodon, the world's #1 imaging filter company. The design process started not with the filter, but with the telescope itself. For a seamless integration with the RASA system, the filter isn't considered an "add-on" to the optical path. Instead, it replaces a piece of placeholder glass already built in.

    This filter was engineered for maximum light transmission. Most light pollution filters block large swaths of the spectrum, producing dimmer images that appear overly blue or green. Astrodon's approach eliminates only very specific wavelengths common to streetlights and other ambient light, still allowing more than 90% light transmission at many wavelengths. You preserve as much light as possible and true colors. Finally, antireflective coatings eliminate halos and internal reflections.

    After each filter is complete, Astrodon individually tests it to confirm light transmission. You'll receive a detailed spectrum report matched to your unit's serial number inside the box, so you can be sure you're getting the best performance.

    Generous 72mm diameter

    When you invest in an astrophotography system like RASA and a high-end filter like this one, you want to be confident you can enjoy it for years. Although most imaging sensors today are substantially smaller, this filter features a generous 72mm diameter, so you can be confident it will work with all the best cameras and imaging sensors of today--and tomorrow.
