Sky-Watcher 'SP-Series' Super Plossl Eyepieces:
'SP-Series' eyepieces minimise spherical aberration, distortion, astigmatism and off-axis colour, whilst their oversized optical elements afford the observer luxurious eye relief.
Stray light is eliminated by the fold back rubber eyecups, standard with every 'SP-Series' eyepiece, and all but the lightest three models feature the security of rubber grips.
Whether observing fine planetary detail or deep space wonder, whether your telescope is a Newtonian, Refractor or Catadioptric, let the high performance imaging of 'SP-Series' eyepieces unlock its potential!
