SVBONY 7-21mm Zoom Eyepiece

  • 7 mm to 21mm adjustable focal length. This 7-21mm zoom eyepiece is equivalent to multiple eyepieces – just twist the eyepiece to change magnifications appropriate to your target.  For example, Jupiter is much larger at the eyepiece than Saturn – you can zoom out, view Jupiter, then switch targets to Saturn, zoom in, and enjoy that, without needing to fumble around in the dark trying to switch eyepieces.  Much easier.  
  • Comfortable 18mm – 16.3mm eye relief, especially if you wear eyeglasses.  Suitable for landscapes, astronomical observations of lunar surfaces, planets, nebulae, clusters and diffuse nebulae.  
  • Fully multi-coated eyepiece. 
  • 6-Element 4-Group premium optical design for superior optical performance
  • Standard 1.25″ eyepiece
  • Standard 1.25-inch lens barrel that is compatible with any telescope that accepts 1.25-inch eyepieces and NO ill fitting ‘safety’ cuts for smooth usage.
  • Rubber eye guard for comfortable viewing and blocking stray light
  • Inexpensive and comfortable to use
  • Full metal body; looks great; 40 degree – 57 degree field of view
