Explore Scientific CLS filter (1.25")

Do you observe from an urban, light-polluted location, but still want to observe mysterious nebulae, galaxies and star clusters? If you're a lover of deep-sky objects, then a variety of deep-sky filters are almost a must-have accessory. By using these filters, deep-sky objects can reveal details that would not be visible without a filter, or only from a very dark sky.

Of course, the Explore Scientific CLS filter can also be used from the city: it helps to combat stray background light caused by light pollution. However, they are not a substitute for dark skies, which means that if you are aiming to detect faint deep-sky objects, you should definitely take your binoculars under a dark, rural sky. The filter transmits a wider wavelength range of incoming light than the UHC filter, making it suitable for observing not only nebulae but also galaxies. Thanks to its transmission range, it can be used both visually and photographically.

Each Explore Scientific deep-IR filter is uniquely tested by the manufacturer, for which a certificate is issued. Premium quality is thus guaranteed.
