Special Features

  • Seamless Magnification Control: A simple twist of the zoom housing adjusts focal length from 7mm to 21mm; Ideal for planetary clusters, lunar details, and deep-sky nebulae observation
  • Extended Eye Relief for Eyeglass Users: 16 to 33 mm adjustable eye relief accommodates eyeglass wearers with zero vignetting; Foldable soft-rubber eyecup ensures comfortable viewing at all focal lengths
  • Versatile for All Observers: Wide 30 degree to 47 degree apparent field of view adapts to planetary and deep-sky targets. Precision stepless zoom mechanism outperforms fixed focal length eyepieces
  • Essentially triple the power of any 1.25 inch telescope eyepiece with the universal Barlow Lens; Suitable for high contrast; high power applications in any telescope
  • Utilizing the 3X Barlow Lens with a longer focal length eyepiece allows you to achieve the same high magnification while benefiting from a larger exit pupil; This configuration typically results in reduced eye strain and improved viewing comfort
