Need help with 90 GPS F/6?
The Sky Rover 90 GPS F/6 is a compact air-spaced triplet apochromatic refractor built around a Super ED glass element. It is intended to deliver strong control of chromatic and spherical aberration in a portable package, suitable for high-contrast visual use and astrophotography.
The triplet design with a Super ED element aims to reduce chromatic error and improve star image quality. Sky Rover reports factory optical verification using artificial-star testing and laser interferometry to ensure consistent performance. The tube includes an integrated rear CAA (field rotator) with an M63 x 1 threaded interface for field flatteners or other back-end accessories.
Compact, lightweight OTA with redesigned dual tube rings, mini handle and a narrow dovetail plate for easier mounting and transport.
2.5" dual-speed rack-and-pinion focuser for fine focusing control and a native 2" visual interface.
Hidden front flange plate allowing small focal-plane adjustments when required for imaging.
The 90 GPS F/6 is presented as a portable APO for both visual observers who want high-contrast views and imagers who need mechanical refinement and a rear rotator for precise framing. Its compact length and included carrying bag (listed by the manufacturer) support field portability.
