Users observing the Deep Sky often use a 30 mm eyepiece, which provides a wide exit pupil that fills the dark-adapted eye with light . In this way,weakly illuminated galaxies and hazes can be distinguished. Eyepieces with large focal lengths (lower magnification) are very important for users for several reasons: their large true field of view makes it easier to find and observe deep sky objects. Many of these objects are very large and are best observed with lower magnification, which your telescope/eyepiece combination can achieve. Even with poor visibility, objects observed with a 30 mm eyepiece at lower magnification are sufficiently sharp.
Foldable silicone eyecups provide maximum comfort for the wearer. People who wear glasses often have the problem that they do not have a full field of vision. Now this problem is a thing of the past. These are excellent multi-element flat field eyepieces that will change your astronomical viewing experience. The patented EMD coating provides high contrast and avoids annoying reflections. Another great advantage of these eyepieces is their outstanding sharpness, which is especially noticeable when observing planets and the Moon, as well as Deep Sky objects. With an upward corrected apparent field of view of 52 degrees, these eyepieces offer outstanding quality compared to a relatively simple Plössl. Argon filling effectively prevents fogging on the inside, and they are protected against dust, fungus and penetration of cleaning fluids. The eyepieces are sealed watertight. This ensures that you can enjoy many years of countless observations with these high-quality eyepieces. The Explore Scientific 52° LER series represents maximum comfort and quality, combined with an excellent price-performance ratio.
