Sky Rover Optics Premium Flat Field 3.5 mm Eyepiece

Description

The Sky Rover Optics Premium Flat Field 3.5 mm Eyepiece belongs to the Premium Flat Field series developed by Sky Rover Optics. This eyepiece range has been designed to provide a flat field of view, excellent aberration correction and outstanding observing comfort.

With its 3.5 mm focal length, this eyepiece is intended for high-magnification observations. Its 60-degree apparent field of view offers an immersive experience while maintaining excellent sharpness from the center to the edge of the field.

Its optical design consists of 6 elements arranged in 4 groups. All optical surfaces feature Fully Multi-Coated FMC treatment to improve light transmission, increase contrast and reduce internal reflections.

The Flat Field design effectively corrects field curvature and provides pinpoint stars across the entire field of view. This feature is especially valuable for lunar, planetary and double star observations.

The eyepiece offers 15 mm of eye relief, ensuring comfortable viewing even during extended observing sessions. It features a foldable eyecup and a standard 1.25-inch barrel compatible with most focusers and astronomical filters available on the market.

Thanks to its lightweight and compact design, the Sky Rover Optics Premium Flat Field 3.5 mm Eyepiece can be used with a wide range of instruments, including refractors, Newtonian telescopes, Schmidt-Cassegrain telescopes and Maksutov-Cassegrain telescopes.
