For spectacle wearers, and especially with short focal length eyepieces, there is often the problem of not covering the entire field of view with spectacles. This problem is now a thing of the past. The flip-up silicone eyepiece holders offeroptimal comfort for your observations with or without glasses.

These eyepieces are excellent multi-element flatfield eyepieces, which will change your astronomical viewing experience forever. The patented enhanced multi-coating treatment or EMD gives you high contrast and avoids annoying reflections. Another advantage of these eyepieces is theextremely high image sharpness that is noticeably noticeable when observing planets and the moon .High-performance eyepieces with short focal lengths (high magnification) from 3mm to 10 mm can not only be used for the observation of the moon, planets and double stars, but also for clear and compact Deep Sky objects. Not only will you be amazed at the size of aplanetary fog or globular cluster, occupying the entire field of view of the eyepiece, but the background sky appears very dark as the effective contrast increases markedly at higher magnification. Good to very good atmospheric conditions are required to produce a sharp image at high magnification. The 52° LER series 4.5mm eyepiece is a popular choice for a variety of telescopes to achieve the highest possible magnification without having to use a focal extender or Barlow lens.
