The 40mm Telescope Eyepiece from Neewer offers a wide 46° apparent field of view and low magnification for both near and deep-sky observations. Fully multi-coated HD lenses deliver good contrast and light transmission, and the 23mm eye relief allows the user to back off from the eyecup for a more comfortable viewing experience with a reduced risk of accidental contact with the eyepiece lens, which can cause vibrations and interfere with views. The eyepiece features a standard 1.25" barrel to be compatible with the most popular size of focuser and accessories, a convenient fold-down rubber eyecup, and a rubberized textured collar to ensure a secure grip when handling it.
