With focal length multipliers (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 longer focal length eyepieces, such as greater eye relief and comfortable viewing at high magnifications.

These high-correction focal length multipliers incorporate a four-lens design that offers excellent image quality across the entire field of view and are preferred choices for visual observations and photography. The combination of excellent anti-reflective coating and telecentric design makes focal length multipliers far superior to classic Barlow lenses.
