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.

Best Achromatic Telescope for Astronomy Beginners

SV503 Astronomical Telescope 102mm F7 ED Refractor OTA

• ED Glass structure: The doublet air-spaced achromatic design with S-FPL51 ED glass reduces chromatic aberration, delivering crisp, accurate color images;
• Large aperture for bright images: The 102mm objective lens with an f/7 focal ratio brings more lights into the scope body and you will get more bright and clear image;
• FMC-coating for crisp image: Ultra-wideband multi-layer coatings and a retractable lens hood provide bright, wide-field images with sharp resolution, perfect for various types of observation;
• Dual-speed rack focuser: The 90mm back focus and dual-speed rack and pinion focuser with focus knob cover make it easy to achieve fine, accurate focus for both visual and photography.
