The 3.5mm Orion Stratus Wide-Field Eyepiece is a high powered eyepiece that is great for viewing details of the planets and moon. With its wide field of view and fully multi-coated optics you get large, bright, high-contrast images.
This was a great addition to my eyepiece line-up since I didn't have anything that approached this magnification. I'm using it with my Orion SkyQuest XT8 Classic Dobsonian Telescope which bring my magnification to 342x. This eyepiece offers a great design that magnifies the usual extremely small aperture of a high-powered eyepiece, which make using it much easier than cheaper eyepieces. Be warned though, this eyepiece will only produce decent images in ideal viewing conditions due to optical limitations.
