The X-Cel LX 3x Barlow Lens (1.25") from Celestron is a new addition to the X-Cel series of lenses. Barlow lenses triple the magnification of your telescope eyepiece, ideal for achieving a closer view of lunar and planetary objects. This three-element apochromatic lens transmits color faithful images with enhanced detail, and fully multicoated surfaces provide contrast rich images with minimal internal reflection.
