Celestron Omni Series 2x Barlow Lens
The Celestron Omni 2x Barlow Lens acts as a doubler to double the magnification of any eyepiece. This eyepiece is designed and built to perfectly compliment the Celestron Omni Series range of eyepieces. However, the barlow lens can be used with any 1.25" Eyepiece.
The Celestron Omni 2x Barlow Lens features a 2-element fully multicoated optics and blacked lens edges for the best experience.
Setting it up is simple. Slide your 1.25" Eyepiece into the barlow lens and tighten the thumbscrew, then slide the barlow lens into your telescope as if it is an eyepiece and you are good to go.
