These 1.25"/31.7mm eyepieces set high-performance standards for modern telescope oculars, ideal as an upgrade to supplied eyepieces with most telescopes. This lower power 20mm is ideal for general observation or wider angle use. The proven 4-element Plossl designs display edge-to-edge pinpoint imaging across their panoramic fields. The 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 !!
