High-performance eyepieces with short focal lengths (high magnifications) of 3mm to 10mm are not only used for observations of the moon, planets and binary stars, but can also be used for bright, compact deep sky objects. Not only will the size of a planetary nebula or globular cluster be impressive if they fill the entire field of view of an eyepiece, but the background sky will also be very dark, since the effective contrast increases significantly with increasing magnification. However, good to very good atmospheric conditions are required for a sharp image to be produced at high magnifications. The 4.5mm eyepiece of the 52 ° LER series is a popular choice for a large number of telescopes in order to achieve the highest possible magnification directly without an additional focal extender or Barlow lens.

The foldable silicone eyecups enable optimal user comfort. As a spectacle wearer, you often have the problem, especially with eyepieces with shorter focal lengths, of having a full view of the field of view with glasses. This problem is now a thing of the past. These eyepieces are excellent flatfield multi-element eyepieces that will change your astronomical viewing experience. The patented EMD coating ensures high contrast and prevents annoying reflections. Another great advantage of these eyepieces is the exceptionally high image sharpness, which is particularly noticeable when observing planets and the moon. With a highly corrected apparent field of view of 52 degrees, these eyepieces offer exceptional quality compared to a relatively simple Plössl. The argon filling effectively prevents fogging from the inside and you do not have to be afraid of dust, glass fungus or the penetration of cleaning fluid. The eyepieces are sealed watertight. This guarantees that you will enjoy these high-quality eyepieces for many years and countless observations. The Explore Scientific 52 ° LER series stands for highest comfort and quality, paired with an excellent price-performance ratio.
