About the Sky Mentor 4mm Plossl Eyepiece 1.25"...
Classic Plossl eyepieces all feature an extra-wide 52 degree field of view, but the Sky Mentor Plossl Eyepieces are loaded with extra features that set them above many older designs!
For a start, Plossl eyepieces are the best eyepieces supplied as stock with new telescopes. Inferior designs such as Huygens, Ramsden and Kellner are blown out of the sky. .965-inch eyepieces should be replaced with an adaptor to fit this universally adaptible 1.25-inch eyepiece.
As it says on the barrel of the eyepiece, all the optics of the Sky Mentor Plossl Eyepieces are fully multi-coated. The dark greenish tinge of light reflected off the lens of the eyepiece means that when observing at night, much more light is passed through the eyepiece than would be if the optics were uncoated. Uncoated optics set off bright white reflections that reduce optical contrast.
The Sky Mentor Plossl Eyepieces have an extra ridge in the barrel for extra safety, holding your eyepieces securely in the telescope focuser.
The rubber eyeguards on Sky Mentor Plossl Eyepieces are a great help in reducing glare from light pollution and outside sources. An unguarded eyepiece might let light from that irritating streetlamp interfere with your viewing, but that'''s no longer a problem! The rubber eyeguard can also be removed to attach digital camera adaptors from Scopetronix!
