The Sky Rover Optics XWA 5 mm eyepiece belongs to the XWA (Extreme Wide Angle) series and provides an extremely wide 110° apparent field of view for a highly immersive observing experience. The optical design uses lenses with fully multi-coated (FMC) surfaces and blackened lens edges to improve contrast and suppress stray light. The updated version features a stainless steel lower barrel, reducing weight and size and making it more suitable for use with giant binoculars and binoviewers.
