Orion 8548 Explorer II 7-21mm Zoom Telescope Eyepiece
The Orion Explorer II Zoom eyepiece lets you change magnification power without physically changing eyepieces
A twist of the zoom eyepiece housing changes focal length from 21mm to 7mm providing a variety of viewing magnification powers
Eyepiece consists of four elements which are fully coated with anti-reflection coatings for clear contrasty views
Exceptionally long 33mm-to-16mm eye relief range allows eyeglass wearers to enjoy the entire view while still wearing their corrective lenses without vignetting
The 125 barrel is threaded for use with like-sized Orion eyepiece filters
