Ultra-Portable Triplet APO Performance for Imaging & Travel
The Sky Rover 90GPS combines premium triplet apochromatic optics with a compact, travel-ready design, making it an excellent choice for astrophotography, wide-field observing, and grab-and-go astronomy. Its 90 mm aperture and fast optical system deliver bright, sharp views with impressive contrast while remaining lightweight and easy to transport for dark-sky trips and portable imaging setups.
Built around a precision air-spaced triplet APO optical design, the 90GPS is engineered to provide excellent color correction and sharp stars across the field—ideal for capturing nebulae, star clusters, and wide-field deep-sky targets. Whether you're imaging with a dedicated astronomy camera or enjoying visual observing under dark skies, the telescope delivers clean, detailed performance with premium refractor optics.
The telescope also features a precision dual-speed rack-and-pinion focuser with an integrated CAA (Camera Angle Adjuster), making it easy to rotate and frame your camera during imaging sessions without disturbing focus. Combined with its sturdy mounting system and lightweight construction, the 90GPS is designed to keep cameras and accessories securely supported while remaining highly portable and imaging-friendly for astronomers who want premium refractor performance in an easy-to-carry package.
Optical Design
The Sky Rover 90 mm f/6 GPS Telescope features an advanced, air-spaced triplet apochromatic optical design built around a premium Super ED glass element. This sophisticated configuration is engineered to deliver exceptional control over both chromatic and spherical aberrations, completely eliminating false color to provide pinning, high-contrast images across the field. Operating at a fast native focal ratio of f/6 with a 540 mm focal length, its optics are fully multi-coated (FMC) to maximize light transmission while minimizing internal reflections. To complement its optical precision, the design integrates an anti-reflective, high-extinction focusing tube with internal baffles to eradicate stray light, yielding pristine visual views and razor-sharp stars right to the edges of an imaging sensor.
Mechanical Rigidity & Mini-Flange Design
Engineered primarily with an emphasis on maximum optical axis stability, the updated telescope swaps the older tube-end rotation mechanisms for a rock-solid mini-flange construction. This effectively prevents sensor tilt and focal plane deflection when carrying heavy imaging packages. To framing your targets with ease, a high-precision Camera Angle Adjuster (CAA) field rotator with an engraved angle scale is integrated natively into the back of the focuser.
Dual-Interface Handle & Heavy-Duty Ring System
Built for seamless mounting flexibility, the telescope features a unique, patented carrying handle that is cross-compatible with both Vixen and Arca-Swiss interfaces, transforming the handle itself into an extra mounting surface. This works alongside newly redesigned heavy-duty dual tube rings that feature multiple side-mounting threaded holes, allowing you to easily side-hang guide scopes, control hubs, or laser pointers.
