Sky-Watcher 'SP-Series' Super Plossl Eyepieces
Super-Plossl Eyepieces (Multi-Coated, Field 52º)

These standard 1.25"/31.7mm eyepieces set high performance standards for modern telescope oculars. The proven 4-element Plossl designs display edge-to-edge pinpoint imaging across their panoramic 52º fields. Utilisation of top quality optical glass, superior multi-layer coatings and edge-blackened elements deliver superb high contrast images.

'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 !!
