The Orion 7.2-21.6mm Zoom Eyepiece has been a popular accessory as part of the Orion GrandView ED line of spotting scopes. The company is now making the eyepiece available as a standalone offering.
Having multiple magnifications all built into one eyepiece allows the observer to quickly zoom to the right power for lunar, planetary and deep-sky observing, optimizing the size and contrast of the object on the fly. Actual magnification range will depend on the focal length of your telescope, but as an example: in an Orion SkyQuest 8″ Dobsonian reflector with a 1200mm focal length, this eyepiece provides a continuous magnification range from 56x up to 167x.
This 7 element telescope eyepiece provides exceptional edge performance, and offers fully multi-coated optics and extra-long eye relief ranging from 20mm (at 21.6mm) to 18mm (at 7.2mm). The apparent field of view angle ranges from 42° (at 21.6mm) to 65° (at 7.2mm). Excellent optics, coupled with a wide field of view make this eyepiece a great eyepiece to pair with any telescope.
