SVBONY TWM1 SV48P Telescope, 90mm Aperture F5.5 Refractor OTA for Adults Beginners, Telescope for Adults & Beginner Astronomers, Telescopes for Deep Sky Astrophotography and Visual Astronomy

Double-speed rack and pinion focuser The gear ratio of the 2-inch rotatable double-speed focuser is 1:10, so that it is easy to achieve accurate focus. FMC glass lens Fully multi-layer coated lens maximizes the light transmittance and eliminates chromatic aberration. 90mm objective lens 90mm objective lens collects a large amount of light thereby providing an enhanced and brighter field of view. Simple operation Quick and easy focusing can be achieved without any tools, even novices can operate it quickly and easily. Beginner telescope It is suitable for beginners to enjoy the beauty of planets and the moon as well as brighter galaxies, nebulae and star clusters. 2 inches rotatable double-speed focuser 2 inches-1.25 inches adapter The gear ratio of the 2-inch rotatable double-speed focuser is 1:10, so that it is easy to achieve accurate focus. Wide rack design 13mm wide rack design can provide smooth focusing thread. Compared to the 70mm model, 500mm focal length and 90mm wide aperture objective lens can collect a large amount of light thereby providing an enhanced and brighter field of view. Let you enjoy the beauty of planets and the moon as well as brighter galaxies and star clusters. FMC lens Fully multi-layer coated lens maximizes the light transmittance and eliminates false colors. 360-degree rotation 360-degree rotation is convenient for photographic composition and visual observation. 130mm Metal hoop Increase the metal hoop to provide installation portability and stability. The length of the hoop is 130 mm.

• 90 mm aperture; 500mm focal length; compared with 70mm and 80mm; 90mm telescope has more light input and a wider field of view; observe the moon and deep space; which is very suitable for astronomy beginners
• Double speed focuser; the 2 inches rotatable double speed focuser; gear ratio of 1:10; precise adjustability for smooth operation
• The focusing mount with metal interface has higher interface accuracy; guarantees the parallelism of the optical axis; and enhances the observation experience
• Fully multil green coated lens; fitted with achromatic glass for good edge-to-edge viewing; fully multi green coated lens maximize light transmission eliminating false color
• 360 degrees rotation; convenient for photographic composition and visual observation; loosen the screw; the focus can be rotated 360 degrees; you can achieve astronomical shooting
