By changing the eyepiece on your telescope, different magnifications can be achieved. All Celestron telescopes ship with at least one eyepiece.
The Omni series is a premium 4 element Plössl optical design, offering minimal internal reflection. Each lens element has multiple coatings to maximise light transmission and contrast.
The X-Cel series is a premium 6-element Plössl optical design with multiple coatings to maximise light transmission and contrast. All sizes offer a large 60° field of view. The range is parfocal which allows you to switch between eyepeices with little or no refocussing.
Eyepiece kits are a great way of having a wide range of magnification options available. Kits always come with a storage case or box, and some also contain a variety of filters - to bring out more detail on planets such as the ice caps on Mars.
