  • 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 43 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
  • Designed primarily for planetary observation "Moon; Jupiter; Mars and Saturn and more" but great for deep sky objects too; comfortable eye relief averaging 16mm across the series; threaded for standard 1.25 inch astronomy filters
  • Wide 58 degree Field of View "FOV" in 2.5mm to 25mm focal lengths; 1.25inch fully multicoated eyepieces give maximum detail and definition across the entire 58 degree field of view; each eyepiece has 5 lens elements in 3 groups
