About this item

  • A twist of the zoom eyepiece housing changes focal length from 21 mm to 7 mm providing a variety of viewing magnification powers; excellent contrast and sharpness making the zoom also of interest for planetary observing
  • Exceptionally long 16 mm to 33 mm eye relief range allows eyeglass wearers to enjoy the entire view while still wearing their corrective lenses without vignetting; the Zoom eyepiece lets you change magnification power without physically changing eyepieces
  • Apparent field of view is 30 degree at 21 mm and 47 degree at 7 mm; rubber traction ring ensures a good grip; the 1.25 inch barrel is threaded for filters; actual magnification range will depend on the focal length of your telescope
  • Eyepiece consists of four elements which are coated with anti-reflection coatings for clear and high contrast views; the large eye lens coupled with the long eye relief means the Zoom provides particularly good viewing comfort; the eyecup can folded down
  • Comfortable viewing at every focal length setting superior to most fixed focal length eyepieces; especially at the shorter focal length settings; precise and stepless adjustment from 7mm to 21mm; a nice value in a quality zoom eyepiece
