The zoom eyepiece eliminates the hassle of changing eyepieces. You can easily adjust different focal lengths by turning it. Therefore, it can replace a range of eyepieces.
At the lowest magnification, celestial objects can be located and open star clusters can be viewed. For observation of the moon, planets and planetary nebulae, the magnification can be increased to the ideal value.
The optical design of this eyepiece corrects spherical aberration, delivering a distortion-free image right to the edge.
The eyepiece is equipped with a variable sleeve for 1.25" and 2" focusers.
