Vixen Apochromatic refractor AP 80/600 ED80Sf Advanced Polaris AP-SM Starbook One (47823)

The Vixen Apochromatic Refractor AP 80/600 ED80Sf Advanced Polaris AP-SM Starbook One is a premium, portable telescope system designed for ambitious beginners and advanced users who want high-quality optics and motorized tracking in a compact setup. The ED80Sf refractor features top-grade FPL-53 glass and a dual-speed focuser, providing sharp, color-free, high-contrast images. Its f/7.5 focal ratio and compact 22.4-inch tube make it ideal for grab-and-go observing and astrophotography.

The Advanced Polaris equatorial mount is lightweight, precise, and easy to use, making it suitable for both new and experienced astronomers. It includes an aluminum gearwheel with 144 teeth and dual-bearing worm shafts for smooth, accurate adjustments. The adjustable slipper clutch allows you to move the telescope freely and then fine-tune its position with rotary knobs, even when motors are installed. Polar alignment is straightforward with either a polar finder scope or a compass, and the mount is compatible with a wide range of accessories.

The Star Book One controller provides simple and versatile control of the right ascension and declination axes, offering multiple tracking speeds for sidereal, lunar, solar, and time-lapse observations. It features backlash compensation, periodic error correction (PEC), an autoguider port, and a built-in red LED for night-time use. The controller is lightweight, compact, and features a clear LCD display with English menus.

The APP-TL130 tripod is stable and portable, retracting to just 60 cm for easy transport and extending up to 130 cm for comfortable use. The tripod legs have retractable rubber covers to protect floors during indoor use and are compatible with other Vixen mounts.
