Use the long focal length Meade Instruments Series 4000 20mm Super Plossl Eyepiece to explore the moon and planets within our solar system, and the wonders beyond.
This eyepiece is made in a 4-element lens configuration with blackened edges and anti-reflection multi-coated optics to produce bright and clear images with accurate color rendition across its wide 52° field of view. It is outfitted with a standard 1.25" diameter barrel to be compatible with a wide variety of focuser drawtubes and accessories, such as diagonals. A long 15mm eye relief allows users the room 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 a convenient fold-down rubber eyecup helps to block stray peripheral light from interfering with views. Meade engineered this model to be parfocal with all other 1.25" Series 4000 eyepieces, requiring little or no re-focusing when changing magnifications during viewing sessions.
