• 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

• 102mm large aperture; large objective lens refractor telescope; high resolution; good light collecting ability; f/6.5 focal ratio; imaging brighter;
• f/6.5 short focal ratio; larger field of view; can collect more light; the image is brighter; and the observation target is clearer and easier to observe;
• Dual-speed focusing; fast focus allows you to quickly move the focus wheel to roughly focus on your target; while slow focus adjusts focus more finely for optimal image clarity;
• Integral hoopd; the tube rings make the telescope more stable and avoid wobbling; and provide a stable support to keep the optical components of the telescope stable relative to each other;
• Easy to assemble and use; the telescope is designed to be user-friendly; it can be set up quickly without additional tools; you can find a lot of fun in assembling.
