With focal extenders (or teleconverters), it is possible to increase the focal length of a telescope, resulting in higher magnification for observing the moon, planets, or small deep-sky objects. This way, you can take advantage of the benefits of longer focal length eyepieces, such as greater eye relief and comfort during high magnification observations.
These high-correction focal length extenders incorporate a four-lens design that provides excellent image quality across the entire field of view and are the preferred choice for visual observations and photography. The combination of excellent anti-reflective coating and telecentric design makes focal extenders vastly superior to classic Barlow lenses.
