Achromatic refractors

102mm (4") f/500 ALT-AZIMUTH REFRACTOR TELESCOPE

SV48P 102mm Achromatic Telescope Refractor with 2.5" RAP Dual-Speed Focusing & Dovetail Mounting Plate for Astronomical Observation

• 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 telescope rings; 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.

Note: The main lens have been corrected completely.
