These standard 1.25"/31.7mm eyepieces set high performance standards for modern telescopes. The proven 4-element Plossl designs display edge-to-edge pinpoint imaging across their panoramic 52° 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 Catadioptic, let the high performance imaging of 'SP-Series' eyepieces unlock its potential.
