This 40mm eyepiece is the longest focal length of the 52 ° LER eyepiece series and with an eye relief of fabulous 27.1mm, it offers unparalleled viewing comfort. The 40mm is also the only 2.0-inch eyepiece in this series. Explore Scientific now has three 40mm eyepieces in its collection, the other two are the 40mm 62 ° series and the 40mm 68 ° series. This focal length is ideal for all deep sky observers who want to find the faintest objects and details with their telescope at minimum magnification. The huge true field of view is perfect for deep sky objects like the Andromeda Galaxy, the Rosette Nebula, and large star clusters and comets.

The foldable silicone eyecups enable optimal user comfort. As a spectacle wearer, you often have the problem 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, but also with deep sky objects. 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.
