'SP - Series' Super-Plossl Eyepieces
Multi-Coated 52º Field

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 multilayer 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!!

Filter Wheel

The 1.25inch 5-position filter wheel requires a light touch to revolve the wheel into its next position with minimal disruption to your scope settings. Each position has a click stop. side of the filter wheel has a 42mm T thread. In eyepiece use you fit the nosepiece on the telescope side and the eyepiece holder on the other. For camera use, the eyepiece holder is replaced with the 42mm Male to Male adapter included in the set giving you the option to connect your T ring or any other piece of equipment that terminates with a 42mm Female thread. A 42mm locking ring is also included as is a 42mm metal dustcap. It is 22m in depth. No filters are included. 

Please note: your focuser will require 20mm of inward focusing distance from the normal focus position to compensate for the thickness of the filter wheel.

Light Pollution Filters 1.25” and 2”

These contrast-enhancing anodized aluminium, optical glass filters are designed to block out the wavelengths of light emitted by mercury-vapour light and other common causes of light pollution, whilst providing higher transmission at critical hydrogen-alpha and hydrogen-beta lines than competing filters. Bright, light-polluted skies appear much darker, and the contrast between object and sky is improved significantly. This contrast-enhancement effect is particularly apparent on nebulae. Unlike stars, emission nebulae give off light in a very narrow range of wavelengths. These filters allow maximum transmission of the important wavelengths of H-alpha, H-beta and doubly ionized oxygen – the ones most commonly emitted by nebulae. Views of galaxies and star clusters are also enhanced, but to a lesser degree. Also improves contrast on reddish planetary detail. Works well in telescopes of all apertures but is highly recommended for use on smaller telescopes up to 114mm diameter, where conventional filters swallow up too much light. Available in two sizes, threaded to fit either standard 1.25” or 2” astronomical eyepieces. Supplied with storage case.
